major application
The resin is used in trucks and passenger cars for parts near the internal combustion engine, such as oil pans and valve covers. Atlac XP810X? has a high molecular weight and is therefore easy to thicken with MgO. In combination with Palapreg? H814-01, SMC can be uniformly colored.

Application Guide
Atlac? XP810X can be processed into LS/LP SMC and BMC with Palapreg? Low Profile Additive (LPA) Depending on the size of the molded part, it is recommended that 300 to 600 ppm of p-benzoquinone be added to the system (based on UP resin plus LPA).
