RTV silicone rubber artificial stone mold

1.Application of RTV silicone rubber artificial stone mold: 

RTV silicone rubber artificial stone mold mainly used for shoe molds, sand casting, sole sampling, plaster models, simple products, products with non-complex patterns, as well as product models with stable size and non-deformation.

2.Operation instruction of RTV silicone rubber artificial stone mold:

RTV silicone rubber artificial stone mold is composed of two components.Component A is white flowing liquid while component B is the curing agent.

Steps of RTV silicone rubber artificial stone mold

   a.take silicone rubber of 100g and add 2% curing agent for  mixing evenly.

   b. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles.

   c.After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame.

Note: For Emblema Moulding RTV-2 silicon rubber is used for pouring or brushing technique. That is to say,

firstly fix the product or sole model to be duplicated onto a plane plate,

then enclose the plane frame with wooden plates to prevent the leakage of the silicon ,

thirdly mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model,

at last  brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.

3.Storage and Precautions of RTV silicone rubber artificial stone mold:

RTV silicone rubber artificial stone mold, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.

 
(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)

4.   RTV silicone rubber artificial stone mold features

       RTV silicone rubber artificial stone mold is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation. Our curing agent is free charged.
