Product Description
Mold Max™ 60
Mold Max™ 60 is a Shore 60A tin catalyzed silicone mold rubber formulated for applications requiring high heat resistance (up to 560°F/294°C). It features a low mixed viscosity and cured rubber exhibits very low linear shrinkage. Parts A & B are mixed 100A & 3B by weight. Pot life is 40 minutes and cure time is 24 hours. Applications include making foundry patterns, flat pattern reproductions and casting low-melt metal alloys such as tin and pewter.
URE-BOND™ 90
URE-BOND™ 90 is a two component, slightly expanding urethane adhesive that offers a strong, rigid bond between many different surfaces. It is often used to bond segments of tooling board as well as other porous and non-porous, rigid substrates.
Working time is 8 minutes, handling time is 4 hours and full cure time is 16 hours at room temperature (73°F / 23°C).
