Zhermack silicone rubber ZA 22 Mold Shore hardness 22 blue soft duplicating silicone 1:1 liquid
Zhermack silicone rubber ZA 22 MOLD Shore hardness 22
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
• Height 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 molds for concrete casting
