Blue silicone rubber kit
Blue Silicone Rubber is extremely high tear, high tensile strength, two components, and tin catalysed RTV silicone rubber. It is designed for casting polyurethane foam, polyester and epoxy parts. Blue Silicone Rubber comes as a kit consisting of 1 gal (9 lb) silicone base and 1 pt (1 lb) blue catalyst. It is a superior product with the following advantages over the RTV silicones:Extremely high tear strengthLow shrinkage, low viscosityExcellent chemical resistanceExcellent shelf agingColor coded catalystLong pot life insensitive to inhibitionVariable cure rateGood dielectric propertiesTypical PropertiesUn-catalysed CompoundBaseActivatorColourWhiteBlueViscosity (cps)50,000-70,000
