Spray up roving and resin curing speed
Spray up roving technical support
The glass fiber spray up technology is a kind of glass fiber reinforced plastic production method which is used to spray chopped glass fiber and resin on the mold and solidify. This production process has certain requirements on the curing speed of resin and the wetting performance of spray up roving. The good spay up roving will be wetted out in the resin quickly, and the poor spray up roving will not be wetted out even if the resin is cured. The white glass fiber can be seen on the surface of the product by naked eyes. There are two possible factors to make the visible white fiber. The curing speed of resin is too fast, and the infiltration of glass fiber is not good. This requires specific analysis of specific problems, but basically for these two reasons.
