Gel Time (mins)
PVAC type low shrinkage additive
Solid contain 36-42%
Lower shrinkage additive, good brightness, .The main advantage is low shrinkage good, but can not color
PVAC type lower shrinkage additive,It has good effect on reducing curing of resin
Safe storage and operation;Does not decompose at room temperature;The SMC prepared has a long storage period and can be rapidly decomposed and cross-linked when it reaches the temperature;The price is cheap.
The amount of initiator shall be controlled:
Excessive dosage: low molecular weight of the product, poor mechanical properties;The reaction speed is too fast, the resin rapidly solidifies and contracts, and the product is easy to crack.
Too little dosage, insufficient product curing.
