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.

Epsilon™ PRO

Epsilon™ PRO is a thixotropic epoxy coating that self-thickens for brushing onto a variety of surfaces.  Compared to original Epsilon™, Epsilon™ PRO offers a longer working time and cured epoxy is semi-rigid, offering better impact resistance.  Mix ratio for Epsilon™ PRO is 2A:1B by volume (100A:44B by weight).  A gram scale is not needed to use this product.

Applied in thin layers, mixed material holds a vertical surface without sagging or slumping. Material wets out uniformly over different surfaces.  Pot life is 22 minutes, with a re-coat time of 3 hours.  All layers should be allowed to cure for 16 hours at 73° F / 23° C and can be accelerated with mild heat.  Epsilon™ PRO is clear and can be easily colored using Ignite™ or UVO™ colorants.  Cured coating has a gloss finish and can be sanded, primed and painted.

Applications: Epsilon™ PRO is suitable for use as a protective, impact resistant coating for EPS or polyurethane foam. It can also be applied to plaster, concrete, wood and fabrics. This product is not sensitive to moisture / humidity and contains no VOC’s.

Alja-Safe™ Acrobat

Alja-Safe™ Acrobat™ is a fiber reinforced "non-sag" version of original Alja-Safe™ life casting alginate. Acrobat is thicker and holds vertical surfaces allowing the user better control for making molds of the face, torso, etc. Acrobat™ reproduces perfect detail from all body surfaces and is good for making temporary molds that can be used to make highly detailed reproductions cast in wax, plaster, Matrix™ NEO™ (polymer modified gypsum), platinum cure silicone or Smooth-Cast™ 300Q ultra-fast urethane resin.
