Detailed Description
China liquid Silicone mold making material for concrete/artificial stone casting
Artificial Stone & Concrete Casting Silicone Rubber
1. Description
C-825/C-830/C-835 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A25-A35 rubber. This is a pourable rubber, but it can be easily thickened with Liquid Thickener or for brush-on application.
Popular product options is C-825/C-830/C-835 are the mold material of choice for high-volume veneer stone production (manual or automated manufacturing). These two-component mold rubbers capture excellent surface detail, offer exceptional dimensional stability and have unmatched lifetime and durability compared to hot melt and polypropylene systems.
Molds made from these room temperature curing systems can be completed in a much shorter timeframe (~4 hour demold) compared to latex rubber molds. When properly maintained, these molds can last for years and produce thousands of stones.
We are China leading liquid silicone moulding material, condensation cure silicone rubber supplier and factory. We sale and export architectural molding silicone, climbing holds molding silicone, crafts molding silicone, mask making silicone rubber from China. Liquid Silicone For Moulds, RTV2 Silicone, Condensation Cure Silicone Rubber Factory China.

Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.
Guochuang Silicone Company is professional medical grade silicone rubber, food grade silicone rubber, shoe sole molding silicone manufacturer and factory. We supply and export artificial stone silicone rubber, plaster molding silicone, prototyping silicone with best quality.
