PRODUCT DESCRIPTION:
SRD 65 is a medium viscosity, economical and easy to handle two component urethane compound. This system cures relatively fast at room temperature producing tough, impact resistant castings. SRD 65 is recommended in applications where a resilient surface hardness is desired while maintaining good flexibility.
