Description of  RTV 2 silicone for GRC products molding

 

RTV 2 mold making silicones are generally named as two-part silicone rubbers which vulcanise, or cure, at room temperature. Part A is a dynamic liquid silicone/Part B is the curing agent (tin catalyst).

 

Main applications of RTV 2 silicone for GRC products molding :

 

Construction of moulds for gypsum, soap, candles, concrete, resin products, artificial (very lightweight) stone, wax or custom moulds;

Decorative building moulds (cornice, column, balustrade, ceilling roses, pedestals,  fountains, mantels, wall ornament, planter etc;

Resin crafts, epoxy resin crafts, poly resin crafts, polyester resin

Advantages of our RTV 2 silicone for GRC products molding :

 

exceptional fluidity and good operability, easy to demold.
Cures at room temperature within 3-4 hours (assuming constant temp of 25 degrees C).
Good tensile and tear strength, low shrinkage (<0.3%)
High duplication levels or longevity
Good resistance to weather, temperature, aging, acid.
Long shelf life (12 months at least) if kept at constant temperatures.
