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.
Woven Rovings
Woven Rovings are compatible with UP, VE, EP and PF resins. Woven Rovings are available with a width range of 50mm～3,000mm and a weight range of 260g/m² ~1,600 g/m² . Other specifications are also available on customer request.
Emulsion Chopped Strand Mats
Emulsion Chopped Strand Mats are made of randomly distributed chopped strands held together by an emulsion binder. They are compatible with UP and VE resins. The roll width ranges from 200mm to 3,120mm. Special requirements may be available upon request.
