SILAB RTV 940 Transparent silicone rubber 

1 Kg. Component A + 1 Kg. Component B. 

SILAB RTV 940 is a bi-component addition cured RTV silicone rubber (base and catalyst with ratio 1:1) which vulcanizes at room temperature.

SILAB RTV 940 is compatible with all plasters, coatings, polyurethane resins and acrylic resins. 

Main application sectors:

Mouldmaking and model-making due to its considerable precision in reproduction, high dimensional stability and high mechanical resistance;     

Ceramic serigraphy due to its considerable precision in reproduction, high mechanical resistance and the excellent laser cutting characteristic;     

Tampography due to its high mechanical resistance. 

Properties:

Reduced viscosity and easy to mix;     

High chemical resistance to the aggressive components of some types of resin;     

Good resistance to laceration (wear and tear);     

High level of accuracy in reproducing very small particulars;     

High dimensional stability over time and non-deformability;     

Considerable resistance to high temperatures and to ageing;     

Excellent non-stick effect.
