We, at Wet A Hook Technologies, Suggest That All Tuffleye Owners Look Through This Page
Tuffleye Core is a special acrylic of the safest and highest quality that will cure (set) with a very narrow spectrum of visible blue light. There are three consistencies now (Finish, Core and Flex) and others are being developed. Tuffleye has been formulated to begin curing within 2-5 seconds and completely harden in 10-20 seconds. It is packaged in light proof syringes. The syringe has a twist off cap that is easily replaced with the provided curved tip applicator if desired. This applicator tip can be trimmed like the tip of a caulking gun to best suit your needs. The syringes are not for re-use.
2. Will Any LED Light Work With Tuffleye?
Not likely. The Tuffleye light has been specifically designed to optimally cure this special material. It has a particular spectrum of light and intensity that will not be matched by purchasing a generic LED light. It is nearly identical to what dentists use in both the spectrum of light, and the intensity of the light. Some dentists have purchased this light to use in their laboratories because it is about one-tenth the cost of their other options.
Most room lighting is capable of eventually curing Tuffleye but it is expected to take several hours, or even days, depending on the intensity of your lighting. You should have plenty of working time in regular room lighting. Some halogen desk lamps may be an exception to this. You can always squeeze out a small dot of Tuffleye on a card and time test it under your lighting.
The Sun has almost all spectrums of light in it. There for it will cause Tuffleye to set very rapidly. Within 30-60 seconds you may start to see it curing, or longer, depending on the sun's intensity. You may not get a fast cure and might have to leave it longer.
For best curing, the Tuffleye light should be held about 5 mm (one-fourth of an inch) from the material being cured. On large applications you should allow the light to remain for a few seconds on each 5-10 mm section of the material.
If you were using the Ultra Violet (UV) light spectrum the answer would be yes! The “visible” light spectrum is farther away from “X-Rays” than UV. Visible Blue light is a very narrow spectrum that is used safely in dentistry and has been for over 40 years. Nevertheless, we provide an eye shield for ease of use and recommend that you observe the light curing process by placing the shield between your eyes and the material. Looking into any light for a sustained time is not recommended and we want you to keep your eye sight good to allow you to tie the best flies and lures. The following chart is what is called “The Electromagnetic Spectrum” and allows you to see why UV light and X-Rays are both forms of Radiation. Eye care and your visual health is why we decided to not use UV light for curing when we introduced this technology to the fishing industry. The second chart s a graph that shows the test results with competitors UV lights compared our Tuffleye visible blue light.
With the proper light, it will begin hardening within 2-3 seconds and completely harden in 10-20 seconds. If this is not the case there may be a problem with either the light (see FAQ #9) or the photo activator in the Tuffleye may be expired. Heat will decrease the shelf life of Tuffleye. If Tuffleye does not cure clear you are not getting a complete cure. This can affect the properties of Tuffleye. Please contact us if you encounter any difficulties with this and we will be happy to assist you.
Yes, if you use the Tuffleye flashlight powered by batteries only. We suggest changing the batteries after 1-2 hours of use. Effective 26/Mar/2007 we introduced an AC/DC light with a warning sensor to indicate when battery power is not sufficient to adequately cure Tuffleye.
The only sure way is with a light meter. Each light is meter checked before shipping to assure its intensity level for best curing. If you have a genuine question about the light, you can take it to your dentist and ask him if he will check it with his light meter. It should give a reading of above 300 mw/cm2. (A reading all dentists should be familiar with.) Don't be surprised if he wants to know where you got it and how much it costs. If this is not possible for you we will be happy to help if you have any questions about the quality of your light.
No. Tuffleye will not yellow even if left in the sun for months. In fact, if you have not completely cured the Tuffleye, it may have a slight yellow cast that will get more clear as it is exposed to more light. When testing Tuffleye Bob Popovics placed a Surf Candy on the dashboard of his car for months with absolutely no yellowing.
Core’s 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 finished that tacky layer needs to be removed.
There are several ways. (Refer to our "Hot Tips" page for more info on this.) "Tuffleye Finish" can be painted as a thin coating over Cores tacky layer and cured. Merely polish the oily residue off Finish and you’ll have a glossy coat. Although it is a bit more difficult, you can also wipe the tacky surface off the Tuffleye Core. You can also use rubbing alcohol. Rubbing this surface with a rag or your finger can also restore the glossy finish. Tuffleye Core is the most durable of all our products surfaces. If the final surface is more dull than wanted (In the water, a frosted finish is not visible.) For show or shadow boxes, many of our testers will paint on a thin coat of our “Top Coat” or nail polish after removing the tacky layer. The following photos show the Tuffleye frosted surface on the left that may come after being wiped with Rubbing Alcohol. The side on the right is a thin coating of Hard as Nails and the bubble is a tiny droplet of water.
Tuffleye Core is as strong or stronger than most epoxies. It is made of an extremely high quality, medical grade, acrylic. While most UV based acrylics available will bend, tear, or break under normal hand strength, Tuffleye Core will not bend, tear or break under that same pressure. The base ingredient of Tuffleye Core is one of, if not the most, biologically and ecologically safe, light cured, materials man has. Epoxies and other UV cured acrylics that we have evaluated cannot make this claim. If you have any questions about our commitment to you and our environment, please call, mail, or email us.

Yes. For smaller flies or applications, Tuffleye Finish will work superbly. Tuffleye Finish is a bit more flexible and flowable than Core. Our testers have used Finish for all kinds of applications. It is excellent for head cement, attaching body parts, etc. However, it is not as durable alone for forming larger flies as with the Core. We recommend using the Core if your desire is the most durable, longest lasting fly.
Remember, the same cap you had to unscrew to get to the Tuffleye, you can place back on the tip of the syringe, or if stored out of the light you can simply pull back slightly on the syringe till you see the Tuffleye material retreat back into the tip then store it away form any light. While using Tuffleye the light proof syringes will protect it from normal room lighting. We suggest when not using Tuffleye you keep the syringes stored in a light proof container. Tuffleye is easy to store if kept in a cool light proof place.
Yes, Chemical MSDS data states 18- 24 months. Tuffleye will begin to be more difficult to cure as the photo initiators begin to age. By refrigeration, when not being used for long periods of time, you can extend the shelf life substantially. Be sure to warm Tuffleye up a bit if bringing it out of refrigeration since Tuffleye is very thick if cold and flows better the warmer it gets. (Most of our samples of the Core, stored at room temperature, have maintained curing ability for over 5 years.)
There is a chemical preservative in some of the nail polishes or other surface coatings that will react with the surface of Tuffleye depending on the type (some do and some don’t) used. We suggest you try the type of coating you have on a small piece of cured Tuffleye before using that surface coating on your Tuffleye flies. (This can also happen to other synthetic fly tying materials you may be using.) The photo below shows what we have found with one of the nail polishes tested. The side on the left is coated with Sally Hansens “No Chip” brand. The yellowish color (chemical reaction) has turned even darker as it has been exposed to the sun. The clear side has a coating of our Top Coat, which has been formulated for this purpose, and does not react to these synthetic materials. Top Coat will air dry tack free in about 2-3 minutes.
