Silicone Rubber Compounds for Concrete Casting

Silicone Rubber Compounds for Concrete Casting special characteristics

For concrete castings to be stylish and stable, alkali resistance, faithful reproduction of even and uneven surfaces, and a durable end product are essential. Our RTV-2 silicone rubber moldmaking compounds provide precisely these qualities, and many others.These RTV rubber compounds allow accurate reproduction of the shape of the original. They are easy to use and are thus used widely in industrial applications, as well as by hobbyists looking to create the perfect replica.

Silicone Rubber Compounds for Concrete Casting features

Workability

The base compound and curing agent are mixed and then poured into the mold to create a silicone rubber mold quickly. Workable time and cure time can be adjusted.

Mold-releasability

The cured rubber releases easily from the mold, so mold-release agents (soapy water, wax, etc.) are unnecessary.
Dimensional stability
These rubbers offer good dimensional stability, with little shrinkage.

Flowability

They have excellent flowability, so the original form is reproduced accurately. This includes even intricate shapes and details such as fingerprints and wood grain.

Heat and chemical resistance

These rubbers have outstanding resistance to heat and chemicals.

Deep-section curability

Moldmaking RTV silicone rubber compound cures uniformly throughout the mold, regardless of thickness.
Non-exothermic
No heat is generated during curing, meaning no adverse effects to the original.
