Two-component RTV rubbers
for moldmaking

Two-component RTV silicone rubber compounds for moldmaking are suitable for mold masters for molding with polyester resin, epoxy resin, urethane foam, wax, plaster, and low-melt-point metal alloys. These RTV silicone 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.

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.

Non-exothermic

No heat is generated during curing, meaning no adverse effects to the original.
