Loon UV Clear Fly Finish Flow – Ultra-Thin UV-Curing Resin for Fly Tying

Loon UV Clear Fly Finish Flow Overview

Loon UV Clear Fly Finish Flow is a UV-curing resin designed for fly tying. It is offered in Flow ultra-thin, THIN, and THICK variants. Flow provides an exceptionally light, controllable coat with no mixing and no waiting, and it remains workable until you choose to cure. Exposing it to direct sunlight or to Loon UV lamps triggers a rapid cure, delivering a hard, clear finish. The resin penetrates fibers and feathers efficiently, helping to dress delicate bodies on tiny midges and to add strength and structure to fur, feathers, or hackle. In the right conditions, it can also act as a substitute for traditional head cement.

What makes UV Clear Fly Finish Flow notable is its versatility. The Flow variant emphasizes a nearly invisible layer with long open time, while THIN and THICK offer different build densities to suit your tying style. It is designed to work indoors or in shaded light until you are ready to cure, giving you control over the shaping process. Once cured, the result is a hard, clear layer that preserves the profile and color of the materials you used.

Why choose UV Clear Fly Finish Flow

• Ultra-thin Flow coating for delicate bodies
• Infinite work time until curing
• Cures instantly under UV light to a hard, clear layer
• Can replace head cement in many applications

Variants at a glance

• Flow ultra-thin for delicate builds and precise shaping
• Thin slightly thicker; adds durability without bulk
• Thick robust layer for stronger bonds on tougher materials

How to use

Apply small amounts with the attached applicator and shape as needed using a rotating vise. You can work indoors or in shaded light until you are ready to cure. When you expose the finished area to direct sun or a UV lamp, cure times are fast and depend on intensity. In bright sun, expect curing in roughly 15 seconds, while controlled UV sources provide consistent results.

Tips for best results

• Choose Flow for delicate bodies, and THIN or THICK to adjust build density
• Ensure a clean surface for the coating to bond
• Cure with the appropriate UV source to achieve a clear, hard finish

Notes: Results depend on materials and lighting conditions. This system is designed to be versatile across many fly tying scenarios, offering a clear, durable layer that can enhance the look and durability of your finished flies without sacrificing flexibility where needed.
