Zhermack silicone rubber ZA 50 LT Shore hardness 50 medium hard blue duplicating silicone liquid 1:1
Zhermack silicone rubber ZA 50 LT Shore hardness 50
Addition-curing 2-component silicone rubber that vulcanizes at room temperature ( RTV ).
Due to the higher degree of hardness, it is very well suited for larger molds, e.g. in concrete casting and for the production of pad printing stamps.
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
• Ceramic stencil printing because of the remarkable precision in reproduction, the high mechanical resistance and the very good property when cutting with the laser
• Art ceramics
• Goldsmith sector
