## Description

Product description R PRO 30 - LIQUID SILICONE RUBBER R PRO 30 is a completely toxic-free addition silicone rubber to make professional medium hardness moulds (30 hardness shoreA). Thanks to its special formula, the catalysis times are 3 hours at room temperature, it has a high dimensional stability (0% linear shrinkage) and high technical and mechanical performance. Really easy to use, with a 1: 1 mix ratio (both by volume and weight). The moulds last over time, they are light blue and excellent to cast resin, wax, plaster, cement and other materials. NOTE : Sulfur-based plasticine is NOT compatible and can inhibit the catalysis of R PRO 30 silicone rubber . EASY TO USE Take the two components (A and B) and combine them according to the proportion 1:1 (every 100 g of A, add 100 g of B); Stir the product vigorously until the mixture is homogeneous; Drain the mixture on the model and wait for the hardening times.

Review: Smooth - mixed well and made a very good mold
Review: Base is a gel, not liquid - The end result is ok at best, but the difficulty to get there doesn’t make up for the mediocre price tag. The gardener pours just fine, but you have to scoop the base out with a spoon despite the directions saying to pour it. The bottle is tall and skinny so you can only get half the contents of the base without a huge hassle. My next batch will be from another company

## 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 30 are very rigid, they last a long time and are excellent for casting resin, wax, plaster, cement and other materials.
- ✔️HIGH PERFORMANCE: R PRO 30 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 high hardness moulds, very elastic and highly resistant to tearing - 30 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.
- ✔️NOTE: Sulfur-based plasticine is NOT compatible and can inhibit the catalysis of R PRO 30 silicone rubber.
