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.

Ferrosilicon is often used as a deoxidizer in steelmaking because silicon combines easily with oxygen to form silicon dioxide. Furthermore, the formation of silica releases a large amount of heat, which also helps to raise the temperature of the steel. Ferrosilicon is an alloy of iron and silicon (average content is 15% to 90%). It is a key ferroalloy used for deoxidation and alloying of steel. Silicon increases the hardness, tensile strength, elasticity and flow limits of steel, improves oxidation resistance and reduces energy losses. In steel making: Used as Deoxidizers and alloying agents In ferro alloy production: Used as reducing agent In Foundry: Used as Inoculants and spheroidizing agents Size:0-1mm, 1-3mm, 3-10mm,10-60mm, 10-100mm, lump, or customized Packing: 1MT big bag or customized

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. 2. Technical Datasheet 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.
