Product Description

Tin cured silicone rubber for artificial stone casting
1. Applications for Tin cured silicone rubber for artificial stone casting:

Production mold casting wax, gypsum, concrete or resins (urethane, polyester, etc. ). Applications include reproducing sculpture, architectural restoration, making candle molds, casting pewter, place couldnt pour rubber over the above etc. For make a mold by brushing (or spraying) rubber onto the model. Rubber will hold a vertical surface and will reproduce the finest detail brushed onto the model in layers until a suitable thickness is built up. The rubber is allowed to cure and a support shell is applied prior to demold. The advantage of making a mold by brushing rubber onto the model is that it minimizes the amount of rubber used, saving material costs.

2. Properties for Tin cured silicone rubber for artificial stone casting:

Brushable Silicone Rubber for Plaster Casting Cornice/Domes Mold that have the best release properties for production casting of resins, plaster, etc. It is a tin silicone rubber that self-thickens for making concrete Spray able -on molds. Properly applied, Mixed 100A: 5B by weight, rubber quickly develops thixotropy when mixed in air. Cured with negligible shrinkage to a durable mold rubber good for production casting resins, foams, concrete, plaster and other materials. Application of a support shell is achieved by spraying over the rubber mold after it has fully cured.

4. Using instruction for Tin cured silicone rubber for artificial stone casting:

Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2g curing agent for mixing evenly (silicone rubber and curing agent must be measured accurately). After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. If you don't have vacuum machine, please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself. Since the less curing agent you add, the slower the mould will curdle, the bubbles will bubble out itself.
