They are widely used for architectural elements, block-outs & hole former, concrete counter tops, flexible form liners, GFRC, manufactured stone veneer, ornamental precast & statuary, stamped & textured concrete, etc. Operation Method: Both pouring and brushing operation methods for our artificial stone casting silicone are available. You can choose the best one as your preference, we can provide thixotropic agent for brushing. Notice What is the hardness should I choose? Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design. Warm Tips: The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry. Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing. Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices). Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include: -Natural or synthetic rubber, vulcanized with sulphur derivatives. -Poly-condensation RTV catalyzed with metallic salts. -PVC stabilizing agents. -Amine cured epoxies. -Sulphur, tin and amines derivatives. -In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.
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. 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. 3.Application
(1) Sharpens stainless steel, carbon steel and much more. Excellent for a variety of knives and tools. It produces strong, keen, long-lasting edges on quality tools (2) This oilstone is used to restore cutting edges on straight-edged tools, such as chisels, knives, plane blades, and precision instruments. The stone is prefilled with oil to save time and eliminate the need to presoak it prior to use (3)- it is easy to control - a sharp knife make a nice clean cut - delicate ingredients look a lot fresher for a longer time if they have been sliced through cleanly - preparing food is faster and more fun with a sharp knife - a dull knife slow you down and easily spoil the food

Ferro Silicon Ferro Silicon has a melting point of 1200�¯�¿�½?�?�°C to 1250�¯�¿�½?�?�°C with a boiling point of 2355�¯�¿�½?�?�°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.

We offer superior quality sponge iron that is also known as direct- reduced iron. Our offered sponge iron is made for high grade, 65-70 fe Min fem-80%, fet-90-92%, s-0.04% max. Loose in form of lumps. Sponge iron filter material In industry through a sponge iron production equipment is widely applied iron phosphorus reduction method, method of reduction of iron ore concentrate, etc., the rolling iron phosphorus or ore concentrate after reduced iron press down into pieces, into the roasting tube into the kiln roasting, produce the high quality reduced iron. Sponge iron filter material for the first time into the deaerator, must first after backwashing, remove the sponge iron residue on the surface of the filter material float ash impurities.
