SMC Raw Material-resin
Dec 16, 2016

Synthetic resins for unsaturated polyester resins and different unsaturated resin resin paste thickening effect and technological characteristics as well as product performance, has a direct influence on shrinkage, surface condition, SMC of unsaturated polyester resin has the following requirements:

① low viscosity and properties of glass fiber infiltration well;

② thickening agent has sufficient reactivity, meet the thickening requirements;

③ cure quickly, short production cycles, high efficiency;

④ cured enough thermal intensity, easy products heat release;

⑤ cured enough toughness, products not something deformation cracks;

⑥ the lower shrinkage.
