PlatSil 71-40 Quart Kit (2.4 lbs)
PlatSil 71-40 is a 1A:5B mix, mid range hardness (Shore A~40) clear platinum silicone mold rubber. Great for making molds for all types of resin casting (polyurethane, polyester, epoxy) and foams without release agents. PlatSil 71-40 clarity makes it most useful for prototype molds where seeing the model helps define parting lines and for filling the mold when casting. Used for prototyping, model making, hobby reproduction and much more. Long mold life and no shrinkage on cure.
Jewelers really like this rubber due to its clarity and release properties.
This Kit Contains 6.5 oz of Part A and 1 Quarts (2 lbs) of Part B.
