The TRANS 40 is a 40A durometer (medium hardness) silicone that is great for making prototype design and production tooling as well as nests, fixtures, architectural, foam, and artistic molds. It is great for making simple one and two piece molds. Vacuum degassing is highly recommended and necessary to achieve highest translucency and physical properties. The TRANS 40 reproduces extremely fine detail and dimensional accuracy. When making 2 part molds, Alumilites UMR mold release, Rubber to Rubber Mold Release, or Vaseline must be applied to prevent it bonding to itself. TRANS 40 is a platinum base silicone and care must be taken to eliminate the possibility of contamination from items containing tin, sulfur, vinyl, amines, and organotin salts, which may cause inhibition.
