RTV Molding Silicone Rubber for Concrete Building Decoration description
RTV Molding Silicone Rubber for Concrete Building Decoration is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silikon is a kind elastic silikon 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.
 
 
RTV Molding Silicone Rubber for Concrete Building Decoration operations
If the customer wants to make large building decoration concrete products and large size molds, the mold should be made of molding silicon with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of molding silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.
 
(Note: our company does not recommend you to add silikon oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silikon oil can be added to soften the mold for easy demold.)
 
Frequently asked questions of RTV Molding Silicone Rubber for Concrete Building Decoration
Why does the silikon rubber mold have few molding times?
The silicon mold has few molding times is due to follwoing reasons: adding too much silicon oil which will destroy the molecular of molding silicon; making the mold for small and fine detailed products with higher hardness molding silicon which is easy to break; making the mold for large products with soft silikon which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silikon to make the mold for suitable products.
