PlatSil® 71-20 our most popular
silicone. Easy 1:1 by volume mix ratio.

A poured blanket mold was made using PlatSil® 71-20 Liquid Silicone Rubber, a unique, 1:1 mix, 4-hour-cure system, which can be used to cast any medium. This gargoyle could now be cast in plaster, concrete or any pourable plastic using this PlatSil® mold. This blanket mold was poured in a single piece, then cut, using a mold key knife, up both sides to create a mold which opens like a book.

New PlatSil® 71-11 user friendly 1:1 by volume
silicone.

Molds made from high-performance PolySil® rubbers are best for casting harsh resins. This gargoyle blanket mold made of soft PlatSil® 71-11 easily pulls off the cast resin part. The smooth, release-free demold of silicone is especially welcome on highly detailed parts.

PlatSil® 71 Series RTV Silicone Rubbers are two-component, addition-cure, platinum-catalyzed, high tear strength, flexible mold compounds. They are tough, and have good tear strength, which make them especially valuable to the mold making industry. They are recommended as mold materials for polyester, epoxy, polyurethane resins, wax in candle molds, and many other materials. PlatSil® 71 Series Silicones are preferred because on curing, they don't shrink, they don't produce alcohol like tin-catalyzed silicones, which can inhibit urethane castings, and they can be heat accelerated to speed the cure.
