There are resins on the market however some simply do not set right through the resin, some are tacky and their manufacturers advise varnish on top. Some resins do not cure all the way through, as a result water ingress into the fly through the uncured resin results in the fly materials falling apart.

The Semperfli team looked at the products available and decided to develop its own range of resins. Our design specifications were that it must be fast setting and have a hard glossy surface. The name was obvious, No Tack UV Resin. We worked with chemists and manufacturers to ensure that we developed a resin that was thin, getting into all of the Fibers and strands of the head of a fly and setting right through the resin leaving no ‘uncured’ resin below the surface ensuring that the resin holds the fly together.

No Tack has among the fastest cure times of any UV Resin on the market! 3 to 10 seconds using a 395nm torch, longer with a 365nm torch.

Hints For Using No Tack UV

No Tack Thin has the viscosity of motor oil, making it easy to apply. It does not set immediately and can be moulded around the head or body of the fly. Use an old bodkin for molding No Tack. Keep a spare as the ideal molding tool to push No Tack UV where required on your fly. Keep your best bodkin for separating Fibers or for splitting Nano Silk to form dubbing loops! Alternatively use a small artists painting brush and paint No Tack onto your fly
