Product Description

Ecoflex™ 5

Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage.  Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.

EpoxAcast™ 655 + 102 Hardener

EpoxAcast655 (formerly Metalset™ A-30) is a versatile aluminum filled castable epoxy that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in3 / 8,390 cm3.

PMC®-780 DRY

PMC-780 is a premium performance urethane rubber that offers exceptional strength, durability and abrasion resistance. PMC-780 DOES NOT CONTAIN MOCA – a known cancer causing agent and hazard. Mixed two parts A to one part B by weight or volume, PMC-780 urethane pours easily and cures at room temperature with negligible shrinkage to a solid Shore 80A rubber.

Pick The One Best Suited For Your Application: Original PMC-780 Dry does not exude oil. New PMC-780 Wet contains a built in release agent to aid in demolding concrete. (Note: “wet” rubber has a higher net shrinkage value over time vs. “dry “ rubber.)
