Platinum Silicone Accelerator

Plat-Cat® Platinum Silicone Cure Accelerator is an additive designed to “accelerate” the cure time of Smooth-On platinum silicone rubber products without significantly affecting the ultimate physical properties. This allows for much faster removal (demold) of a part or rubber mold from the original model. The accelerator is added by weight to Part A and should be thoroughly mixed into Part A before adding Part B.

Note: Adding the accelerator drastically reduces the pot life (time you have to mix and pour material) of the liquid rubber product.
