Dimethyl silicone oil is a hydrophobic organic silicon material that is widely used in our daily lives due to its unique characteristics. What are the characteristics of dimethyl silicone oil as a defoamer and lubricant?

1. As a defoamer: Due to its low surface tension and insoluble in water, as well as in animal and vegetable oils and high boiling mineral oils, dimethyl silicone oil has good chemical stability and is non-toxic. It has been widely used as a defoamer in industries such as petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, and papermaking. As long as 10-100PPM of silicone oil is added, it has a good defoamer effect.

2 as a release agent: Due to the non adhesion between dimethyl silicone oil and rubber, plastic, metal, etc., it is also used as a release agent for various rubber and plastic products forming and processing, as well as in precision casting. Using it as a demolding agent not only facilitates demolding, but also makes the surface of the product clean, smooth, and with clear texture.

3 as lubricants: Dimethylsilicone oil is suitable for lubricating rubber, plastic bearings, and gears. It can also be used as a lubricant for rolling friction between steel and other metals at high temperatures, or for friction between steel and other metals. However, due to the poor lubrication performance of methyl silicone oil at room temperature, it is generally not recommended as a lubricant between metals at room temperature.

4 as additives: Dimethyl silicone oil can be used as an additive for many materials, such as as as a brightener for paint. Adding a small amount of silicone oil to the paint can prevent the paint from floating or wrinkling, improve the brightness of the paint film. Adding a small amount of silicone oil to the ink can improve printing quality. Adding a small amount of silicone oil to polishing oil (such as car polish) can increase brightness, protect the paint film, and have excellent waterproof effect.

Dimethyl silicone oil is widely used in our daily lives, bringing us many conveniences. Currently, there are hundreds of derivatives of dimethyl silicone oil, which is not the end point. In the future, there will be more derivatives of dimethyl silicone oil, and their applications will be more widespread.
