Dimethicone is a hydrophobic silicone material. Because of its unique characteristics, it is widely used in our lives. As a defoaming agent, what are the characteristics of lubricants?


1. Use as defoaming agent: Since dimethyl silicone oil has a small surface tension and is insoluble in water, animal and vegetable oils and high-boiling point mineral oils, it has good chemical stability and is non-toxic. It has been widely used as a defoaming agent in petroleum and chemical industries. , medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10-100PPM silicone oil is added, it will have a good defoaming agent effect.

2. Use as a release agent: Due to the non-stickiness between dimethyl silicone oil and rubber, plastics, metals, etc., it is also used as a release agent for the molding and processing of various rubber and plastic products, and in precision casting. Using it as a release agent not only facilitates demoulding, but also makes the surface of the product clean, smooth and clear in texture.

3. As lubricant: Dimethyl silicone oil is suitable as lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for the rolling friction of steel against steel at high temperatures, or the friction between steel and other metals. However, since the lubricating properties of methyl silicone oil are not particularly good at room temperature, it is generally not recommended as a lubricant at room temperature. Metal-to-metal lubricant.

4. As an additive: Dimethyl silicone oil can be used as an additive for many materials. For example, it can be used as a gloss enhancer for paint. Adding a small amount of silicone oil to the paint can make the paint non-floating and wrinkle-free and improve the brightness of the paint film. Add a small amount of silicone oil. Adding a small amount of silicone oil to polishing oil (such as automotive varnish) can improve printing quality by adding it to ink, which can increase brightness, protect the paint film, and have excellent waterproof effects.

Dimethicone is widely used in our lives and brings a lot of convenience to our lives. Currently, there are hundreds of derivatives of dimethicone. This is not the end. In the future, the derivatives of dimethicone will There will be more objects and more extensive applications.
