| RC-542 is a flame retardant elastomer formulated for room temperature meter-mix dispensing systems and short mold cycle times. Excellent physical properties can be obtained with a room temperature cure without the utilization of mercury, MOCA, or TDI. RC-542 conforms to UL94vO flame resistance and is yellow card certified. RC-542 exhibits a very low viscosity, allowing for better mold-flow. |
