(Bill Harms), That was in the Garrison book. It’s a spiral rod. Was it redish or purple? http://www.cpadhesives.com  (1-800-454-4583)  Ask for the rodmakers pack. The principal advantage of the copolymer resins over straight resorcinol resins is their significantly lower cost; the price of phenol is much lower than resorcinol. during the late 50's and sixties. But most of us, ahem, guys are wired to not give much hoot about "colors" aren't we? I was thinking the other  day about glue entering the fibers of cane. Any questions? (Tony Young). Can be easily mixed by volume, and thinned with denatured alcohol. Poor water resistance is rarely a problem with wooden objects intended for indoor use, anyway. We only used resorcinol, and although the purple stains have long gone away from my hands and arms, I do still have my coveralls which are covered with purple globs and stains!!! Winter-grade, according to Pardey, is superior with (go figure) lower curing temps, better gap-filling, and less worry over clamping pressure. For harsh conditions, however, I believe resorcinol to be the best choice, as it always has been. The only product that I have found locally is about five years old. It is imported into the US by Custom Pak, and they list two formulations on their website, a Medium and a Fast cure. I sort of remember it being a little different to maroon but maybe not. I'm answering your first question as your web search has thrown up a few other points. I wonder why the colour would be different in the US? This cost advantage apparently is achieved without any significant loss in joint performance. This means that the glue resists to the boiling test where a sample is subjected to several cycles of boiling and drying. I don't know about the other adhesives  (the only one I use other than resorcinol is URAC, and that far less frequently). Repeated or prolonged exposure to the substance can produce target organs damage. Maybe we just to need to find a chemist and convince him somehow that its worth the effort. U.S. resorcinol market revenue by application, 2014 - 2025 (USD Million) (John Silveira), It most certainly will. See how much you know about different glues by taking this quiz. Of the other adhesives you have found, Cascophen is a type of resorcinol glue but has one liquid and one powdered component, it is available from most chandlers as it is used in boat making. (Tom Smithwick). The invention relates to a resorcinol-formaldehyde resin/resorcinol-phenol-formaldehyde resin composite curing agent and a preparation method thereof. Another one that's not quite right but close enough for this level of explanation is brick red. The have distribution centers on both coasts. (Ralph Moon), My thanx for the pointers @ the download from Power Fibers. PL Premium 10-fl oz Brown Multi-Purpose Construction Adhesive. Uncured resorcinol has a relatively short shelf life of about two to three years, depending on storage temperature. This has been confirmed by Wolfram Schott. Good point, Tony. Even if you are building nodeless, I think the heat treating is done before scarfing and gluing. Their bonds can be undone with hot water. They can be reached at 800-861-3192, or at aircraftspruce.com. When gluing the joint be sure to coat both surfaces with a liberal amount of glue before joining together. (Bob Brockett), Call them. The glue does set up fairly fast. Since most of the others are neutrally colored, it'd be hard to tell if they do the same (though the epoxies all seem quite a bit thicker than resorcinol). It may have been a change of manufacturers, and it may have actually been an improvement. There was no data sheet with the glue. The resulting glue lines are still the characteristic resorcinol plum brown, but they seem thinner and less noticeable at this early stage than ordinary resorcinol glue lines. After a thread colour discussion with a customer in the UK who wanted a lavender colour that in Canadian English turned out to be Royal Purple, for colour I finally resorted using the numerical values for the primary colours red, blue and yellow and plugging them into Photoshop. Aerodux is a certified adhesive for wooden airframes. I have planned on sacrificing the first coat of varnish at times. Product DescriptionApplication:Resorcinol is a kind of important organic intermediates,which is used for rubber materials, adhesive, uv absorber, dye, medicine and etc. I was interested in your comments on glue usage from past UK makers. Type I moisture resistance is a stellar quality. I would not use this and think this explains why this product is being withdrawn. Titebond is so good and easy to use and get that it's what I've ended up using anyhow. (Don Anderson), Given that resorcinol is the only colored adhesive, the thought occurred to me to stain the adhesives with oil based "paint" stains and see if one could learn anything. One solution I've heard of, but never tried (and I think this is the one listed in Garrison), is to add powdered titanium white (paint) to the resorcinol to lighten it up. Brian Pitcher I have been informed by Chempoint that Aircraft Spruce buys from them regularly so that shelf life is not an issue. (Paul McRoberts). Let you know what they say, since I'm not clear looking at their site listing again. Resorcinol is used to produce resorcinol.formaldehyde (RF) resin to improve the adhesion of rubber and other materials in rubber products, wood adhesives, flame retardants, UV stabilizers, dyes, and others. Paraformaldehyde decomposes to formaldehyde which is carcinogenic. MUTAGENIC EFFECTS: Not available. then again if you have sanded off the glue you might not be able to distinguish the difference, I suppose. You are quite correct, Tony - the glue lines were quite dark, but quite clearly dark maroon rather than than what I would call purple. What are the Advantages of Resorcinol Glue? Resorcinol phenol formaldehyde (RF) Like epoxy, resorcinol phenol formaldehyde – normally referred to as resorcinol formaldehyde or RF – is a structural adhesive classified ‘Exterior’, ‘High Hazard’ to BS EN 301. So it never gets back all of what you’ve driven out. I recently spoke to the DAP folks and was told that they plan to discontinue production of Resorcinal. Its use has declined since the 1990s due to the ease of use and versatility of epoxy glues and fillers. Additionally, rising usage in applications like UV stabilizers, etc., coupled with inherent advantages offered by the chemical is anticipated to add to the growth of the resorcinol … I have a Driggs taper rod made nodeless using resorcinol that's over 15 years old. You can’t easily tell, but the claret color persists in the glue lines. (Chris Obuchowski). (Bob Brockett). I took a rod with me to Grayling in 2002 I think that was made with resorcinol. They look like exactly the same color as the spots on the newer rod. Its amazing what you can get in a few minutes with Google. 11. Search the classic fly rod forum - dap discontinued it, but it's still available through another distributor: DAP products and Borden chemicals no longer produce the stuff. I admit I’m probably the only person in the world nostalgic for the true purple glue line. Given the shelf life of the stuff, this might be a good candidate for a group-buy. I emailed Custom Pak to see if they would fax me one but they did not answer. I don't know. Excess glue shouldn’t be completely wiped away, as you need glue at the glue line to be absorbed into the wood. Choosing the right glue will help a quick fix last longer. Maybe 300? The total amount of mixed glue you can make is 11.8#. Years ago, I spliced a few strips before planing, and later heat treated them. (Chris Obuchowski), Wolfram Schott covers this in his "Bamboo Under the Microscope" which can be downloaded from the Power Fibers site. (Gary Marshall). Repeated skin exposure can produce local skin destruction, or dermatitis. You could likely distinguish  the glue line anyway. (Paul Blakley), I have never used resorcinol before but I have some that Todd gave me to try out and I want to use it on the 2 rods I have ready to glue up. There appear to be some U.S. suppliers. If you think you are seeing a twist, you are right. If I remember correctly,  I read that there is a powdered die that you can add to resorcinol to help eliminate the purple glue line. Try: Epoxy is the only adhesive suited for constant water contact but for typical outdoor projects, Titebond II, polyurethane, and urea formaldehyde will all hold their own. The Spanish word they use for the process is "change" (cambiar) not "return" (devolver) which gives a lot of insight on the way the situation is thought about here. Somebody looked at it and said something like the glues nice but too bad about the purple colour. Inflammation of the eye is characterized by redness, watering, and itching. I have not pursued this yet. This would assume the stain would not preferentially migrate to the fibers. Even just gloves and safety glasses make a huge difference. After that they are just left there for looks, and should not be dug out. (John Channer), Resorcinol thinned with alcohol does penetrate into the bamboo fibers, but only at the cut ends (think of thin glass straws and capillary action). We call it that because we are selling you a full gallon of the liquid resin (9#), plus the appropriate amount of powder hardener to catalyze -that gallon, which = 1.8. My last five rods have been bonded with some resorcinol that I imported from Tony Young (now off the list and on his way to a new life in NZ) and this glue leaves the famed red/wine glue lines. Exchanges are grudgingly allowed only in some cases. (Brian Creek), The glue showing up on the rod after the varnish was a problem this is what I did. College chemistry was a third of a century ago. In either case, the pigment would need to be colorfast over time, and not affect bond strength. There are many different shades of claret, and it must have been confusing to a lot of people - now Uni calls it “Wine.”. It seemed fine to me. (John Smith), Is bamboo considered wood? But then again, as John Rupp mentioned a few days ago, AircraftSpruce.com sell it in pints for $19.90!!! Urac has a similar MSDS. The dust can clog the pores in the wood and greatly reduce glue penetration. I've used resorcinol on dozens of rods with excellent results every time. (Timothy Troester), Depends on who you are. Staples should be removed from all gussets. With the Aerodux I use the glue line is a plum/brown color perhaps the pure resorcinol is more distinctly purple? I'd place resorcinol at #4695 and consider the colour purple to be around #511. The amount of tissue, damage depends on length of contact. Surfaces cut with a sharp blade or saw are good, the pores are open. As a courtesy (BE NICE!) Personally, I think resorcinol is the best glue you can use though the others are so good that there's no point to my mind in debating things. But it doesn’t fill gaps like epoxy. I don't know why I didn't think to relate the colour I've been trying to explain to the Pantone chart in the first place. What is the best formula that people are using? For myself, I did just purchase a pint kit from Aircraft Spruce, so I'm okay for now. I still can't figure out what colors puce, or sea foam, or unicorn's hair are. I had wondered what was used particularly as neither the Hardy nor the Allcocks rods that I have show glue lines whereas the Sharpes one does. That was the main attraction of the glue for me, to get the strength of resorcinol without the walnut flour filler. (Tony Young). For wood gluing, the volume of phenol-resorcinol used far exceeds straight resorcinol. 1-16 of 73 results for "resorcinol glue" Skip to main search results Eligible for Free Shipping. (Frank Stetzer, Hexrod, Taper Archive, Rodmakers Archive), Why not go right to  the source. I’m guessing the trick is to NOT use too much water. I believe someone came up with a formula to "bleach" the color out of Resorcinol glue, but I also think I heard that the effect was not permanent for some reason. You can end up squeezing out most of the epoxy and have a very weak joint that looks nice. (Don Anderson), Reminds me of when I first started tying my pheasant tails with Uni-thread 6/0 “Claret” color more than 20 years ago. (Gary Marshall). Emphasis must be placed on “small nails” as their job is only to lightly secure the gusset to the joint until the epoxy or glue dries. Considering the problems I had with nodeless rods using every other glue that's really saying something but the sentence in "the bible" about it being purple prob stopped a lot of people from even considering it and I tended to try to get to the bottom of what this purple thing was to the point that I was convinced that half the world was calling what I saw as claret purple. When the parts are clamped together, excess glue should squeeze out around the entire parameter of the joint. Now let’s talk about colors of flamed bamboo in order of darker to lighter. (Mike Biondo), Just emailed them to see if that's a kit of a gallon each of the resin & catalyst, or 1/2 gallon of each for a gallon total. the liquid resin is an alcohol-water solution of a partially condensed resorcinol-formaldehyde resin containing a suitable reinforcing cellulosic filler. Their purpose is not structural, and using large nails will actually weaken the structure. The sequence I use - your milage may vary - is this: To anyone interested in trying resorcinol, I'd suggest the British Aerodux liquid catalyst version. Model #2505716. I will probably have to try dying a lighter colored glue, as others have suggested. It’s true that hide glue isn’t very water resistant, but this is more an advantage than disadvantage because it allows repairs to be done more easily. All exterior/marine/aircraft ply is glued with resorcinol. If I'm reading this right. Some folks are careful about sifting the powder, but to tell the truth, I don't bother anymore, and haven't had any problems with gaps or glue lines. We certainly didn't order a 20-foot container of Gore-tex based on a colour described as basically royal blue but sort of skyish. Christmas Missives - Chat Room - Photo Galleries - Line Conversions - The Journey - Extreme Rodmaking - Rodmaker's Pictures - Donate - Store, Here is the direct link to alternate resorcinol supplier. Somewhere there must be an optimal time to do this. Advantages of using our products for glulam include: Long working open times are available Fast cure speeds Structural durability The pigment to use is as manufactured wholesale by the Tioxide (IE: Titanium Oxide) Company. It is supplied as a white powder and mixes with water to give a paste. Another problem I've had with resorcinol is even after sanding the glue off, after varnishing and time somewhere a resorcinol stain shows up on the surface of the rod where I didn't get all of it off. As for time I usually leave my blanks in string for three weeks before continuing with the process but I have a friend who is happy to continue within a few days of gluing up. After binding you have a few minutes to straighten, but just a few, before things stop moving. It is a good bet the oil based stains would not, at least some of them. I can send you some paraformaldehyde if you want to experiment. (Alberto Poratelli), A couple of drops of TransTint dye should do the trick. Anyone with any experience there? Resorcinol based glue also owes its moisture resistance to naturally occuring phenols. Dies soaked into seam. It sounds worse than it is. burning, sneezing and coughing. I know it is not the same as on the  cans. (I was expecting a quart total.) Clearly I'm not as mad as I thought I was going and my search for a non claret-coloured resorcinol can end. Thank Heavens that in our voracious and greedy modern commercial culture we still have a few companies like these who still take a bit of trouble. It is however more than adequate! But claret-colored resin aside, is there any performance reason anyone is familiar with to choose one over the other. (Brian Smith), If I use resorcinol on a blond blank, will the glue stain (discolor) the flats? Read both of the downloads - Schott makes some enlightening observations based on his  test results. Areas where joints and gussets are always visible such as the cockpit tend to look nicer if very small brass aircraft nails are used to secure the gussets during gluing. We specialized in reproducing custom redwood windows, doors, sash and other millwork for victorian homes. I have measured moisture content by carefully weighing a sample, baking then re-weighing. This is important to avoid starved glue joints. Is the colour on your overalls at the violet or the red end of the spectrum? Bob:  received your question about the amount included in the gallon kit of resorcinol. How long should I wait before beginning to remove the slight twist I ended up with on this one? (Todd Talsma), Sand/scrape or I use a file. (Dave Burley). They charge a reasonable price for the product, so it cannot have anything much to do with bottom line. Is this true of other glues? This is a 30 year old hartley powerboat. One part is a resorcinol-formaldehyde resin that is deficient in formaldehyde; and the other is simply formaldehyde or a formaldehyde donor. Maybe if I get some good feedback on how to eliminate the powder -- and thus much of the resulting increase in rod diameter across the flats -- I'll try it on a personal rod. (Al Baldauski), I just found out Aircraft Spruce ships worldwide via DHL, so I can get the stuff down here in Chile. It is expensive but mine has stayed good a long time (years) kept in the refrigerator. (Tony Young). So, I went with Nyatex and Epon. Evidently, he did not lose any sleep over it, and I guess I should not either. Though perfect tight fits look very nice, they are not needed and can sometimes be a problem with epoxy, so don’t get it too tight. (Tony Young). What species do fish for with your bamboo rods? Denatured alcohol, acetone, and krazy glue all have the same health risk rating as paraformaldehyde (2). I've gotten it from them in the past and they were selling it in pint cans at the time. Do I dare? Epoxy will fail when subjected to same wet or heat conditions . Peter I'm a bit jealous, unfortunately I don't have the same kind of customer service down here in Chile - I can buy the glue locally but I have to buy it in 5 gallon containers! I have a feeling that is highly unlikely. Make some test pieces with different clamp pressures, and see how they break. I suspect the long nose of nanny government in the recent change, but that may just be the paranoia of a grumpy old SOB, too. Aircraft failures have been recorded where the cause was cited to be poor glue selection during construction. It blends into the fall foliage. I have a Dickerson 7614 taper rod not fished quite as hard but same story. I would wait a couple more days. Slightly hazardous in case of skin contact (sensitizer). Hoagy said you can add universal pigments (I forget which, I think white and mustard) to the glue and it will turn it tan, but if you have to heat straighten, it will turn pink where it was heated.
