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.

Free Form™ SCULPT

Free Form™ SCULPT is a two part sculpt-able epoxy clay that requires no firing and will self-cure in a short time to an extremely hard and durable state with virtually no shrinkage. SCULPT is 30% lighter than similar products and holds vertical surfaces better. Users can sculpt larger, stronger pieces with more control over weight distribution. Free Form SCULPT has an ultra fine particle size that gives the user the ability to sculpt finer detail with better precision using tools or shaping by hand.

A mirror-like, gloss finish can be achieved by smoothing SCULPT with water before it cures.
