Unit Size Net Weight Pint 1 lb Gallon 8 lb Five Gallon 40 lb Silicone Thinner is a non-reactive silicone fluid that will lower the mixed viscosity of tin cure (condensation) or platinum cure (addition) silicone rubber products.Properties Silicone Thinner offers the following advantages: A lower mixed viscosity (A+B) means that the rubber will de-air faster when vacuuming. Mixed rubber (A+B) will flow better over intricate model detail. Silicone Thinner will lower the ultimate shore hardness (durometer) of cured silicone rubber. Pot life (working time) is increased in proportion to the amount of Silicone Thinner used. Disadvantage: Ultimate tear and tensile strength are reduced in proportion to the amount of Silicone Thinner added, however knotty tear properties of the Mold Max Series rubbers are unaffected.Documentation Technical Bulletin Special Order Items PRODUCT ADVISORY: The products listed below are currently SPECIAL ORDER items and require pre order.
