PTM&W Industries PT8902 Two component urethane casting system
Categories:	Polymer; Thermoset; Polyurethane, TS
Material Notes:	PT8902 is a unique two-component urethane casting system that has very high cured properties, which allow it to produce extremely durable parts and shapes that have very good heat resistance. Three hardeners with different working times and very low mixed viscosity with PT8902 Part A make it very easy to handle and cast by hand pour or machine casting techniques. The low viscosity fills thin sections and complicated shapes with ease. The cured material is very tough, and it can be demolded from the toughest mold configuration without breaking. The natural white color of PT8902 can be easily tinted or pigmented for a broad range of colored parts. There is a black version of Part B2, for a cured color of black. PT8902 is Certified to USP Class VI requirements.
