Spray-up Process

 

A mould is sprayed with a mixture of catalyzed resin and chopped fiberglass roving (fiberglass cut to specific length using a chopper gun). Then the glass-resin mixture is well compacted, usually manually,for complete impregnation and deairing.After curing the finished composite part is de-molded.

Assembled Rovings for Spray-up

Assembled Rovings for Spray-up are compatible with UP, VE and PU resins. They deliver properties of low static, excellent dispersion and good wet-out in resins.

Hand Lay-up Process

 

 

The reinforcement, in form of fiberglass strands, mat or woven roving, is first laid into a mold which 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.
