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.

Plasti-Paste™ EPOXY

Plasti-Paste™ EPOXY is an epoxy-based version of Smooth-On’s popular urethane Plasti-Paste™ products. It is a two component, fiber-filled epoxy designed for vertical surface application. Part A is a paste and Part B is a liquid. Mix ratio is 2A: 1B by volume or weight. Pot life is 40 minutes and cure time is 16 hours at room temperature depending on mass. Applying heat can reduce cure time. Mixed material holds a vertical surface without sagging and cures very rigid and strong.

Liquid material can be colored with UVO™ colorants and cured epoxy can be sanded, machined and painted with acrylic enamel paints. This plastic can used as a support shell or mother mold material to reinforce rubber molds during casting. It can also be used for creating themed environments, creating art or special effects. This epoxy is also a powerful adhesive and can be used as a repair material for a variety of industrial applications.
