Anti-yellow Agent - White Crystal, Melting Range 100-116â°c | Yellowing Resistance, Color Retention, Temperature Stability, Oxidation Protection

Owing to the expertise in this domain, we the manufacture and supply wide range of anti-yellow agent.

I. Basic performance and application :
T317 yellow stain resisting agent can improve the yellow stain resistance of resin and some pigments. It can protect the coat from yellow stain due to early oxidation in the environment or room temperature where oxidation occurs easily. Also, it can prevent the coating film generating yellow stain at a certain high temperature. It enjoys better compatibility without influence on other performance of powder. It can play a role of color retention for ordinary pigments under temperature difference.
