Zhermack silicone rubber ZA TT 3040 Shore 30
Zhermack silicone rubber ZA TT 3040 Shore hardness 30
Addition-curing 2-component silicone rubber that vulcanizes at room temperature (RTV).
Being remarkably fluid, it is suitable for duplicating models with small undercuts.
Compatibility extends to all plasters, waxes, polyurethane and acrylic plastics.
properties and application
• High chemical resistance to aggressive components of some types of resin
• High tear resistance
• 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 molds for concrete casting
