PC-8500

Single-Component Lightweight Casting Compound

PC 8500 is a lightweight epoxy coated material designed for casting & potting. It is a single component, syntactic foam which is formulated so there is no advance preparation before use. Its porosity helps provide a structural matrix for added liquid resins. This structure provides greater physical properties while maintaining a specific gravity less than water.
