## Description

R PRO 20 Silicone Rubber for Silicone Medium Hardness Moulds,Silicone Mould Making kit for DIY, 100% Safe,high Tear Resistance,1:1 Mix Ratio

## Features

- BEST RUBBER FOR MOULDS: 1:1 mix ratio (both by volume and weight), it hardens at room temperature. The moulds made with R PRO 20 last a long time and are excellent for casting resin, wax, plaster, cement and other materials.
- HIGH PERFORMANCE: R PRO 20 silicone rubber faithfully copies even the smallest details, it allows you to make 15% more castings than other silicone rubbers and the moulds have no linear shrinkage. Pot life: 45 minutes - Hardening time: 3 hours. It is a very fluid rubber with easy mix ratio and does not need to be degassed.
- HARDNESS: with this catalyzed rubber you can create medium hardness moulds, very elastic and highly resistant to tearing - 21 hardness ShoreA;
- MOULDS PERFORMANCE - The physical life of the moulds depends on how it is used (cast materials, frequency, etc.). Casting abrasive materials such as concrete can quickly erode the details of the moulds, while casting non-abrasive materials (such as wax) does not affect the details of the moulds. Before storing, the moulds should be cleaned with a soap solution and dried completely. In the case of a bivalve mould, you have to assemble the two parts of the mould.
- NOTE: Sulfur-based plasticine is NOT compatible and can inhibit the catalysis of R PRO 20 silicone rubber.
