Checkerspot Cast PU 1004 was developed to balance impact resistance and tensile strength, including in cold temperatures. Potential applications include board sidewalls in for snow- and watersports, and other applications that require a rigid material.

This two-component polyurethane casting system formulated with estimated 58% biobased content (ASTM D6866). It gels in 17-21 minutes and can be removed from the mold in 12 hours. For accelerated curing, post-bake at 80C (176F) for 30 minutes. The pigmented material (with dispersion loading at 2% by total weight) cures to a Shore hardness of 70 D.
