Dimethylsilicone oil is a kind of hydrophobic silicone material, because of its unique characteristics, it is widely used in our lives, dimethylsilicone oil as a defoaming agent, what are the characteristics of lubricant?
1 As a defoamer: due to the small surface tension of dimethyl silicone oil, and insoluble in water, animal and plant oil and high boiling point mineral oil, good chemical stability, and non-toxic, used as a defoamer has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper and other industries, as long as 10-100PPM of silicone oil has a good defoamer effect.


2 As a release agent: due to the non-viscosity of dimethyl silicone oil and rubber, plastic, metal, etc., it is also used as a release agent for various rubber and plastic products molding processing, and for precision casting. Using it as a release agent is not only convenient for release, but also makes the surface of the product clean, smooth and clear.


3 for lubricants: dimethyl silicone oil is suitable for rubber, plastic bearings, gear lubricants. It can also be used as a lubricant for rolling friction between steel and steel at high temperatures, or friction between steel and other metals, but because the lubrication performance of methyl silicone oil is not particularly good at room temperature, under normal circumstances, it is not recommended as an inter-metal lubricant at room temperature.


4 As an additive: Dimethyl silicone oil can be used as an additive for many materials, such as paint brightening agent, add a small amount of silicone oil to the paint, can make the paint does not float, does not wrinkle to improve the brightness of the paint film, add a small amount of silicone oil to the ink, can improve the printing quality, add a small amount of silicone oil to the polishing oil (such as automotive polishing oil), can increase brightness, protect the paint film, and has excellent waterproof effect.


Dimethylsilicone oil is widely used in our lives, bringing a lot of convenience to our lives, at present, the derivatives of dimethylsilicone oil have reached hundreds of kinds, this is not the end, the future, dimethylsilicone oil derivatives will be more, more widely used.
