Tuffleye will beat up epoxies all features in every situation. Glue cures with LED-light, so the glue is easy to handle. Light uses the blue, visible light spectrum, as in the Medical and Dental profession, because of it's safety factor over UV light. The visible blue light is used to activate the catalyst in the material. The more intense the beam, the faster the cure. The light should be held about 1/4 inch (5 mm) away from the material being cured. Glue begins to cure after 3 - 5 seconds and after 10 - 20 seconds fly is ready to use. We advise the use of the protective eye shield provided when curing the material. Direct Sunlight will also cause the "Tuffleye" material to cure.
Three different glues: Core, Finish and Flex. Tuffleye Core is as strong or stronger than most epoxies. It is made of an extremely high quality acrylic. While most UV based acrylics available will bend, tear, shrink, or break under normal hand strength, Tuffleye Core will not bend, tear or break under that same pressure. The base ingredient of Core is one of, if not the most, biologically and ecologically safe, light cured, materials man has. We recommend Core if your desire is the most durable, longest lasting fly. Tuffleye Finish is a bit more flexible and flowable than Core. It is excellent for making smaller flies, head cement, attaching body parts, etc. Flex is a right choice when you want to have a flexible feature for your fly.
Top Coat product has been formulated to give you a beautiful and long lasting clear coat of acrylic to complement and protect your work without damaging chemical reactions. Top Coat dries fast and can be simply brushed on like the coating materials you currently use. Paints are less likely to smear or bleed with Top Coat. Thinner which can be added to the Top Coat and allows you to obtain the consistency that fits your needs the best.
Cores tacky outer layer is a chemical reaction to air (Oxygen). All light cured acrylics have it and it has pros and cons. The pro is that you may add eyes, overlays, wings, legs, etc., to your fly and Tuffleye will not only act to help stick them in place, but an additional covering of Tuffleye will irreversibly bond to itself. The con is that once the fly is tied, many tiers desire to eliminate the tacky surface. You can get rid of the tacky outer layer by using rubbing alcohol and there's also several other options.
