Please remember to order the silicone cross-linker (component B) for silicone rubber RTV 3255 heat resistant separately!

Silicone RTV 3255 is particularly suitable for the production of casting moulds for casting metals with a low melting point (e.g. lead or tin) and epoxy casting resin. Heat resistant up to approx. 250° C.

Application:

Stir silicone compound well before use. Carefully mix silicone RTV 3255 (component A) with silicone curing agent (component B) in a weight ratio of 100:5. Always measure the exact proportions, preferably using a digital scale. It is best to work at a room temperature of 23° C and a humidity of 50 %. The higher the room temperature and humidity, the shorter the pot life and the faster the curing time. The silicone can be thickened with Aerosil powder.

If the object to be moulded is made of metal or another smooth material, first clean and degrease the object. Wipe with a cloth soaked in acetone or rinse with acetone. Prime the object by dipping, spraying or brushing with a suitable agent (with the exception of silicone), then leave to air dry at 25° C for at least 30 minutes. Then pour silicone RTV 3255 slowly and evenly around the object.
