GI-739 Tin-Based Brush-On Silicone

GI-739 is a thixotropic (resistant to flow) tin catalyzed silicone designed to be used when
painting or spraying onto vertical surfaces. GI-739 does not contain the mold rotting thixo-
additives widely used today, but offers the end user the same ease of use and detail
reproducibility. When catalyzed with one of our library life extending catalysts (see
supplemental products) and stored correctly, a longer life of the cured mold should be
expected. Its high tear strength, elongation and tensile strength make it an excellent choice for
any mold making application. It is also resistant to inhibition by most common mold making
substrates, eliminating the need to use mold sealers.
