## Overview

R PRO 20 is a professional-grade, non-toxic platinum silicone rubber with a 1:1 mix ratio that cures at room temperature in 3 hours. It offers medium hardness (21 Shore A), exceptional detail replication with zero shrinkage, and durability that yields 15% more castings than competitors. Perfect for crafting high-quality molds for resin, wax, plaster, cement, and other materials.

## Description

R PRO 20 is a completely toxic-free addition silicone rubber to make professional medium hardness moulds (21 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 (+15% of castings compared to other silicone rubbers). 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 20 silicone rubber.

## 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.
- ✔️NOTE: Sulfur-based plasticine is NOT compatible and can inhibit the catalysis of R PRO 20 silicone rubber.

*by A***R on Reviewed in the United States on 6 February 2023*

Update 6-FEB-2023:Now reading of an inhibition issue with some SLA resins not cured for many hours. Will top-coat molds with non-inhibiting coating and re-cast. Will update rating upon results.Original Review:Instructions followed to a tee:-Used identical single-use syringes from the same batch to precisely measure each part.-Combined and mixed thoroughly for 5 minutes.-Poured into open top 3D Printed "sheet" molds (1.2mm thick with various top-down areas.)Results:-Tops cured well - looks good so far...-Peel up sheet - Still uncured where not exposed to air.-Sticky messI will be purchasing a different silicone for our use, as 3 days+ is not an acceptable when expecting 3 hours.

    Molto buono e resistente
  
  

*by L***I on Reviewed in Italy on 14 December 2023*

L’ho usato per farmi degli stampi in piano per delle protesi per il viso. Materiale molto buono e resistente consigliato. La prima volta ne avevo preso troppo poco e non ero riuscito a finire di colare a pieno e riempire tutto lo stampo quindi ne ho comprato altro ricolato sopra e non ho avuto nessun problema sembra tutta una sola colatura… approvato

With a 3d printed mold or normal plestic mold it will not curr right and will remain sticky
