Content: 2kg (1kg A + 1kg B)
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.
Because of the short processing time very suitable for processing with dispenser and mixing systems as well as for spraying.
Features and Application:
• High chemical resistance to aggressive components of some types of resin
• Very 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
• Production of vacuum hoods due to the very short processing time
• For processing with dispensers and sprayers to produce large-area molds or vacuum hoods
