Shore A 90 hardness Overview
Info: 75-90 is our hardest and strongest polyurethane rubber. It is used for making tough, durable molds, liners and stamps for casting, forming and texturing concrete. This firm rubber is also popular for making industrial parts, rollers, gaskets, bumbers, pads, and more.
Mix 2 part A and 1 part B to make polyurethane mold rubber, after mixing, cures at  room temperature to flexible, high strength, mold rubber.  
This rubber can be used  for casting rubber parts when a mole release is used.
Mold Release Info: For releasing this rubber from a smooth non-porous original/plug an aerosol such as "Polease-2300"
or "Stoner"
is suitable, located in my store. Porous objects such as plaster, concrete or wood should first be sealed to create a smooth surface from which to apply the mold release. These mold releases are in spray cans and cannot be shipped international.
This rubber can be colored using "Liquid Pigments"
in my store.
Due to the Tan/Brown color tinting this material will be offset by its color.
I also have "Mixing and Measuring containers and Mixing Sticks"
in my store.
