PlatSil 71 Series Silicone Rubber
PlatSil 71 Series Silicone Rubber
PlatSil 71 Series mold rubbers are two-component, addition-cure, platinum catalyzed, high tear strength, flexible mold compounds. They have tough knotty tear strength which make them especially valuable to the mold making industry. They are recommended as mold material for polyester, epoxy, polyurethane resins, waxes and many other materials. PlatSil silicones are preferred because on curing, they do not shrink, they do not produce alcohol like tin-catalyzed silicones which can inhibit urethane castings, and they can be heat accelerated to speed the cure.
