UTC Thread wax is designed for all nylon fly tying threads. It is a special light formula that prevents fraying of the thread and helps add “bite” to the thread. The added “bite” helps hold delicate materials in place with a minimum of thread wraps.
This is particularly important when tying small flies. It is also useful when used as a dubbing wax with very fine dubbings.
Fly tyers with rough skin on their fingers will find that the wax also helps in making the handling of materials much easier.
