| VA-286 is a tough, heat-resistant polyurethane formulated for vacuum assisted casting systems and short mold cycle times. Excellent physical properties can be obtained without the utilization of mercury, MOCA, or TDI. VA-286 has a longer gel time than VA-285, allowing for larger castings. VA-286 can be easily pigmented. |
