Wilsor Polyester Resin 0.25 Liter

Application

Wilsor polyester resin is a synthetic resin that cures after the addition of a hardener. It is used for making yachts, spoilers and sculptures, among other things. The strength of polyester resin is obtained by using reinforcement materials such as glass mat, kevlar or carbon. The resin is applicable to substrates such as stone, steel, polyester and epoxy, provided they are grease-free and roughly sanded. Polyester resin does not adhere to epoxy, polyethylene and Teflon.

Reinforcement material

Because polyester resin is inherently brittle, it must be reinforced with a reinforcement material such as fiberglass, carbon or kevlar mat. These are available as woven mat or shredded mat.

User Manual

1. Sand the damaged surface and make sure it is dry, dust- and grease-free.
2. Add hardener: about 2% to a maximum of 4% relative to the resin. More hardener accelerates the cure. The 250 ml and 500 ml containers use a BP tube; rub it well against the wall of the mixing cup for proper mixing. The 1 and 5 liter containers use MEK hardener.
3. Apply the resin with a brush and place the reinforcement material in the wet resin.
4. Press the reinforcement material firmly so that it is completely soaked with resin. Avoid air bubbles.
5. After curing, protruding fibers can be cut away. Sand the surface smooth and apply a coating if desired.
