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 3.8L silicone base and 473ml blue catalyst. It is a superior product with the following advantages over the RTV silicones:
- Extremely high tear strength
- Low shrinkage, low viscosity
- Excellent chemical resistance
- Excellent shelf aging
- Color coded catalyst
- Long pot life insensitive to inhibition
- Variable cure rate
- Good dielectric properties
