Product Description

EZ-Spray® Silicone 22

EZ~Spray® Silicone 22 are sprayable silicones which cure quickly to soft rubbers with high elongation and tear strength. Liquid silicone is sprayed through the EZ~Spray® Junior Cartridge System which is an economical alternative to expensive spray equipment. After a suitable thickness is attained, EZ~Spray® Silicone 22 cures in about 45 minutes. EZ~Spray® Silicone cures with negligible shrinkage to strong, durable silicone rubbers good for production casting of polyester, epoxy or urethane resins, gypsum, concrete and other materials.

PC-3®

Smooth-On PC-3® Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.

TASK™ 9

TASK™ 9 Colormatch is a high performance urethane casting resin that features very high compressive strength and tensile strength. TASK™ 9 is clear amber, which makes this plastic very easy to color using SO-Strong™ or IGNITE™ colorants. With a mix ratio of 1A:1B by volume, TASK™ 9 is easy to use and a low mixed viscosity (300 cps) ensures minimal bubble entrapment. Pot life is 7 minutes and cure time is about 60 minutes (depending on mass).
