Features

  • Ecoflex rubbers are water white translucent and can be color pigmented with Silc Pig pigments for creating a variety of color effects. You can also add Smooth-Ons Silicone Thinner to further lower the viscosity. THI-VEX silicone thickener can be added by weight to Ecoflex silicones for brushable applications.
  • Ecoflex rubbers are suitable for a variety of applications including making prosthetic appliances, cushioning for orthotics and special effects applications (especially in animatronics where repetitive motion is required).
  • Note: Ecoflex 00-10 cures with a tacky surface.

Description

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. 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.

    • Soft yet strong, mold-maker's ideal for complex and tricky shapes.
Size: Pint Unit
Smooth On products all day long, love this company and all their materials. Eco Flex, though tacky when cured, has a remarkable low shore hardness and is very strong. Mold-making for extremely tricky undercut heavy pieces can be achieved with this stuff, so long as a mold-frame or mother-mold is in use for overall shape-stability. Takes pigments very well. ... show more

    • Amazing for Very Delicate Work
Size: Pint Unit
Used this to create a cast of a crumbling, very old (130 years) plaster crown molding. The salvaged pieces would turn to dust if handled with anything more than the lightest touch. The crown molding is native to the original build of the house, and we wanted to preserve it. Hence, we decided to make a silicone mold of the pieces if possible. Seemed impossible. Not impossible. This is one of the softest silicone casting materials around. We poured it very gently over some of the largest and most complete pieces we managed to retain. We used a 2" depth over the pieces. Surprised the hell out of us when this stuff captured every fine detail of these decaying remnants. From it we were able to cast and create much longer mold (6') of the crown molding. Hence, we preserved the original look of part of this house with this material. I remained convinced the softness of this material and the excellent fluidity vs viscosity of the liquid silicone played a vital role in casting something this delicate. We even managed to preserve some of the original plaster cast after taking it out of the finish mold. The high elasticity coupled with the overall softness of the hardened silicone made it easy to remove from the source material. That seemed remarkable to me. Highly recommend this product for casting delicate work. ... show more

    • Silicone rubber leaks during delivery
Size: Pint Unit
I bought 2 sets. One set is broken and the surface of the bottles are so sticky (the silicone rubber leaks), but it still works fine. Another one’s packaging is prefect.
