Fiberglass Powder Chopped Strand Mat for Hand Lay-up Process


Powder Chopped Strand Mats are made of randomly distributed chopped strands held together by a powder binder. They are compatible with UP, VE, EP, and PF resins. The roll width ranges from 200mm to 3120mm. Additional demands on wet-out and decomposition time can be available upon request.

Hand Lay-up Process:

The reinforcement, in form of fiberglass strands, mats, or woven roving, is first laid into a mold that has been coated with a release agent and a gel coat. Then a resin mix is applied by hand using a brush or spray gun. A roller is then used to ensure uniform impregnation, complete glass wet-out, and removal of any trapped air bubbles. This operation is repeated until the desired thickness of the structure is obtained. After curing at room temperature or under heating conditions, the finished parts are formed.
