Most Popular RTV Silicone Rubber Compounds for Concrete Casting

RTV 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.

RTV 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.
