Usage Suggestions:
Crystalline polyester resin is mainly used to improve leveling and mechanical properties. The test shows that it is helpful to the appearance of matting formula and reduce gloss.
For special products, SCT1307 is not recommended to be used alone, but can be used with amorphous polyester resin. The matching ratio of amorphous polyester and SCT1307 is recommended to be determined by the customer according to the experiment results.
Adding SCT1307 to amorphous polyester can significantly improve the leveling performance and mechanical performance of the coating. The weather resistance of the coating is related to the amorphous polyester resin used.
