Tin Based RTV Silicone Mold Rubber 30 Shore A White Silicone Liquid Rubber For Plaster Mouldings

High Strength Pourable RTV 2 Silicone Liquid Rubber For Making Molds For Gypsum And Concrete Decor

Product Description
Silicone liquid rubber is called Tin cure silicone rubber which is also called condensation-cure silicone mold rubber, these are high-tear silicone mold rubbers that are known as the “work horse” of the industry because of their performance and economy.

RTV2 silicone rubbers for molds are liquid or pasty silicone elastomers reticulating at room temperature. After the addition of appropriate catalyst they form a stable and not reversible compound characterized by high elasticity and mechanical resistance. Owing to their high chemical-mechanical properties combined with easy workability, the RTV2 silicone rubbers are suitable for making flexible moulds and matrices to reproduce, starting from an original model, hand-made articles of any kind and form, in different applicative sectors. Silicone moulds, owing to their anti-adherence features, allow an easy demoulding of models and assure extreme faithfulness in the reproduction of details.

Application of RTV-2 silicone liquid rubber

mainly used for the reproduction of hand-made articles, from silicone rubber matrices: resins (Unsaturated polyester resins, epoxy resins, polyurethane resins and acrylic resins), Polyurethane elastomers, Natural waxes and synthetic, Plasters and cements, Low-melting point alloy and Wood imitation (PU resin).

Features of RTV-2 silicone liquid rubber

Cold vulcanize with the appropriate catalyst
Can be applied by direct pouring or by spreading
Easy mould building, no need of particular equipments
High elasticity, easy demoulding also for objects with undercuts
Extreme faithfulness in the reproduction of details from any original model

Instruction of RTV-2 silicone liquid rubber:

How to use the silicone rubber to make a mold

Step 1: Prepare and clean the master piece. Please make sure your original moulds clean and dry.
Step 2: Mixing part A and part B evenly. Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step 3: Vacuum degassing, this step takes less than 10 minutes. Otherwise, it will cause a cross-linking reaction, and no further steps will be available.
Step 4: Pouring or brushing. After released the bubble, we can pour/brush the silicone rubber on the master piece.

Package of RTV-2 Silicone Liquid Rubber

Part A base silicone: 20kg,25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
