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.

Habitat Cast N Coat™

Habitat Cast N Coat™ is a filled, two component (A+B) liquid epoxy that can be cast solid or thickened for brushing on / troweling on to vertical surfaces. Material cures to a rock-hard solid with negligible shrinkage.
Mix ratio is 1A:1B by volume. Working time is 85 minutes and material cures overnight (at room temperature).  UVO™ or Ignite™ colorants can be added to liquid Cast N Coat™ during mixing to create a variety of color effects. Cured epoxy can be sanded and painted with acrylic paints.
Habitat Cast N Coat™ certifies to the highest flame rating available (ASTM E84, Class A), making this material ideal for public space fabrication applications. Also, it does not contain VOC’s, phthalates or crystalline silica (a known carcinogen) and is safe for making elements used in proximity to animals/reptiles and aquatic life.
Epoxy bonds permanently to itself or a variety of surfaces and can be applied as a fire rated protective/decorative coating to EPS or rigid foam, wallboard, plaster, wood, PVC and more. Habitat Cast N Coat™ is also an excellent repair cement and bonds permanently to itself, PVC, Plexiglas™ (acrylic), wood, many metals, plastics and foams.
