of fresh silicone rubber for making molds.  Use it for making molds for industrial parts, jewelry, figurines, soap, candles, etc.  It is very soft and stretchy, with a durometer of 28 Shore A. This silicone is used for making cast "block" or thinner "skin" molds.  It flows very nicely and picks up incredible detail.
Please note: Our silicone RTV rubber is sold by weight, not volume.
**AM128 Pourable is a 10:1 mix ratio by weight.  You must use a digital gram scale for the correct measurements. We sell a very accurate digital scale on Ebay that is great for measuring silicone rubber by weight.**
Among the many things you can cast into molds made of  AM128 Silicone RTV Rubber Pourable are:
Urethane (polyurethane)
Polyester casting resin
Plaster
Hydrocal, Hydrostone
Low melt metals like pewter or tin (mold life can be short)
Cement, Concrete

**Silicone does stick to itself, glass and anything made of silica.  Please use a petroleum based mold release, like the one we sell on Ebay, if you are pouring silicone into a silicone or silica based mold.**
ALWAYS SHAKE PURPLE CATALYST VERY VIGOROUSLY FOR 90 SECONDS BEFORE POURING.  POUR CATALYST IMMEDIATELY AFTER SHAKING IT!
