Product Property
7937 resin in benzene anhydride and anhydride and standards as the main raw material of o-type unsaturated polyester resin, has been dissolved in crosslinking monomers such as styrene, has lower viscosity and moderate reactivity.
Main Application
The resin has property of low viscosity, large amount of fillers should be added, so it has excellent operation performance. After curing, it has excellent strength, rigidity and toughness, as well as low curing shrinkage rate.The products can be fast solidifying , low shrinkage, high intensity and bright color.It is suitable for normal temperature and middle temperature fixed fossil quartzite products.
