Overview

Riverruns' fly tying resin is a UV-curable adhesive sold as a thin glue formula, used to coat and seal fly heads and bodies during tying. It fits fly tiers who already use a UV light to cure resin coatings rather than solvent or epoxy based finishes.

UV-curable resins cure on demand under a UV light rather than needing a fixed working time like two part epoxy, which lets a tier build up thin coats and cure each one before adding the next. The listed formula is described as thin glue, suited to detail work like coating fly heads or eyes rather than building a thick, domed body. The listing does not state bottle size or cure time, so factor that in if you are ordering to match an existing UV light or workflow.

Who it's for

Fly tiers who already work with UV-cured finishes and want a thin viscosity resin for detail coating, such as fly heads and small bodies. Not the pick for someone starting from scratch without a UV curing light on hand.

Pros and cons

Pros
  • Cures on demand under UV light
  • Thin viscosity suited to detail coating
  • From a brand focused on fly tying supplies
Cons
  • Bottle size not stated
  • Cure time not specified
  • Requires a separate UV light to use

Performance notes

UV-curable resin stays liquid until exposed to UV light, which lets a tier apply a thin, even coat and cure it in seconds rather than waiting out an open working time the way two part epoxy requires. A thin formula spreads into fine detail on a fly head without pooling the way a thicker resin can.
