TC-5140 40A Platinum Silicone
Important! This is a platinum silicone system. Platinum or addition cure silicones may be inhibited by some pattern and mold surfaces! A small test is recommended to determine suitability.
TC-5140 A/B is a room temperature, 40A addition/platinum curing silicone rubber designed for making molds and parts. Featuring exceptional tear strength, low viscosity, 1:1 mix ratio, and a quick demold time, this system is user friendly while producing high quality finished products. When used to make molds, the TC-5140 A/B is translucent enough to see through when casting into the mold cavity. May be pigmented using our silicone pigments in the Silicone Additive Section.
Release non-porous patterns or molds with 2500 or SupraLease PTR mold release. 2350 or pure petroleum jelly or fragrance free Vaseline may be used as a release for porous surfaces.
