Product Description
Ecoflex™ 00-45 Near Clear™
Ecoflex™ 00-45 Near Clear™ is a very soft, platinum silicone that is clearer than other Ecoflex™ silicones. Versatile and easy to use, Ecoflex™ 00-45 Near Clear™ rubber is mixed 1A:1B by weight or volume and cures at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing. Cured material is skin safe and certified by an independent laboratory.
PMC™-121 30/WET
The PMC™-121 Series urethane rubbers feature convenient one-to-one by volume mix ratios. PMC™-121/30 Wet is exceptionally strong and abrasion resistant for soft urethane mold rubbers. It exudes oil that aids in demolding hard plasters and concrete.
