Silicon monoxide, white cubic crystal or brown powder, is insoluble in water, soluble in a mixture of dilute hydrofluoric acid and nitric acid, reacts with boiling caustic soda solution to form silicate and hydrogen, can be oxidized by halogens, and is easily oxidized in the air to form a protective film of silicon dioxide and become inactive. It has strong reducing properties at high temperatures and can reduce water vapor, carbon dioxide, limestone and other substances; it is often obtained by sublimation of silicon dioxide and elemental silicon powder in a high vacuum above 1400�°C in industry; it is often used to prepare optical glass and semiconductor materials.
Uses Used to make optical glass and semiconductor materials. The overview, physical and chemical properties, preparation methods, and uses of silicon monoxide are edited and compiled by Ding Hong of Chemicalbook (2015-11-16) Chemical properties White cubic or loess-colored amorphous powder. When heat-treated in air, the loess-colored powder turns into white powder. Melting point is greater than 1702�°C. Boiling point is 1880�°C. Relative density is 2.13. Insoluble in water, Chemicalbook is soluble in a mixture of dilute hydrofluoric acid and nitric acid. Uses Silicon monoxide powder is extremely active and can be used as a raw material for the synthesis of fine ceramics, such as silicon nitride and silicon carbide fine ceramic powder raw materials. Uses Used in the preparation of optical glass and semiconductor materials Uses As a raw material for fine ceramics, it has important value. It can also be evaporated in a vacuum and applied to the metal reflector used in optical instruments as a protective film. It can also be used to manufacture semiconductor materials. It is also used in optical glass.
Silicone rubber surfactant (Organic silicone surface additive) Application:
It can be used as a spray modifier, foliar absorption aids, activation agent, widely used herbicide, liquid nutrients, growth regulators, insecticides, fungicides, which do not decompose the original pesticide, can greatly reduce the surface tension of the solution, reducing the contact between the droplet and the leaf angle, surface enhanced the liquid in the plant or pest surface wetting, adhesion, and a spreader, thereby improving efficacy.

Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc.
As an experienced Silicon Dioxide manufacturer and supplier, we has been supplying and exporting Silicon Dioxide for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Application:
Because of its special, excellent physical and chemical properties, Siwin-PDMS can be used in many different industries, including:
MECHANICAL FLUID: Excellent viscosity-temperature characteristics, thermal and chemical stability, shear-breakdown resistance, compressibility, and rubber compatibility make it outstanding for mechanical/ hydraulic uses. Typical uses include hydraulic stabilizers and damping media.
SURFACE-ACTIVE MATERIAL: Added to vinyl plastisols, it improves the flow characteristics, and de-aerates and lubricates the surface of the completed part.
LUBRICANT: The fluid provides excellent lubrication for most plastic and elastomeric surfaces. Lubricity with metals depends upon the combination involved. Care should be taken to select suitable metals for pumps and other items with moving parts.
COSMETICS AND SKIN PREPARATIONS: it is an important ingredient in hand creams, skin protestants, suntan lotions, and hair grooming aids because it forms a non-greasy, protective film that resists water and waterborne irritants, yet allows the skin to breathe. Literature is available that details the use of the fluid in cosmetics.

4. Operation Instruction
Step 1: prepare the original molds
Make sure your original molds perfect. fix it on a board. And fix the original mold on a board , then used four piece of board to enclose the original molds .
Step 2: Take 100 G parts A and add 100G parts B and mix them evenly.
1.Weigh the two part exactly by electronic weight..
2.Mix part A and part B evenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. Whats
more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step 4: Pouring casting or Brush operation
Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .
2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which wont be easy to flow away and easy to brush .
3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .
