Zhermack Silicone Rubber ZA RTV 30-60 White, super resilient, medium-hard duplicating silicone
Zhermack silicone rubber ZA RTV 30-60 Shore hardness 30
Addition-curing 2-component silicone rubber that vulcanizes at room temperature ( RTV ).
Compatibility extends to all plasters, waxes, polyurethane and acrylic plastics.
Features and Application:
• High chemical resistance to aggressive components of some types of resin
• Extremely high tear strength
• High level of fidelity in very small details
• High dimensional stability over a long period of time
• Remarkable resistance to high temperatures and to aging
• Outstanding non-stick effect
Main areas of application
• Manufacture of molds and models because of the remarkable precision in reproduction, high dimensional stability and high mechanical strength
• Art ceramics because of the high dimensional stability, the remarkable fluidity and the good mechanical strength
• Manufacture of concrete molds because of the remarkable precision in reproduction, the high dimensional stability and the high mechanical strength
