Silicone defoamer is a white viscous emulsion. It has been used in various industrial fields since the 1960s, but large-scale and comprehensive rapid development started in the 1980s. As an organosilicon defoamer, its application fields are also very wide, attracting more and more attention from all walks of life. In the chemical, paper, coating, food, textile, pharmaceutical and other industrial sectors, silicone defoamer is an indispensable auxiliary in the production process. It can not only ...

1 Classification of amino silicone oil Amino silicone oil can be divided into single-end type, double-end type, side-end type, copolymer type and mixed type according to the position of the amino group in the polysiloxane molecule. Classified by end groups, there are amino silicone oils such as methyl, methoxy and hydroxyl. The end group is methyl called "inactive amino silicone oil", which is more suitable for processing cotton and silk fabrics. The end groups are hydroxyl and methox ...

The application of silane coupling agent can be roughly summarized into three aspects;(1) Used for surface treatment of glass fiber. Silane coupling agent can improve the bonding performance of glass fiber and resin, and improve the strength, water resistance and weather resistance of glass fiber reinforced composite materials. In 2004, the silane coupling agent used in glass fiber accounted for more than 50% of its total consumption. Among them, vinyl silane, amino silane, methacryloxy silane, ...

The water-based defoamer is formulated with dimethyl silicone oil, white carbon black, emulsifier, etc., and is made into a water emulsion dispersible defoamer using emulsification technology. All raw materials and links are non-toxic, with the characteristics of fast dispersion, fast defoaming, long suppression time, stability and no delamination.Foam and foam often accompany people’s life and production, and sometimes need to use it, such as flotation, fire extinguishing, dust removal, washin ...

In the defoaming agent industry, I believe everyone knows that polyether defoamers and silicone defoamers have their own characteristics. What are their characteristics and what are the differences? Something is short, so let Jingqi defoamer manufacturers tell you.Polyether defoamer:In recent years, it has been widely used and researched. The main component is formed by ring-opening polymerization of ethylene oxide (EO) and propylene oxide (PO). It is a water-soluble surfactant with excellent no ...

The leveling principle of silicone leveling agent: surface tension is the main driving force for the leveling of the coating film, but poor surface tension is the main source of surface defects of the coating film. Increase the surface tension of the coating film to achieve a balance of surface tension, which is very beneficial to the flow and leveling of the coating film, but it cannot be done. Therefore, people have to reduce the surface tension of the coating film to eliminate the difference ...

Because it looks like asphalt, it is also called high-elastic rubber asphalt waterproof coating. It is called "Four Not Fears" because it is not afraid of water leakage. , Not afraid of aging, not afraid of cracking and deformation, not afraid of puncture. The knife is pierced into the paint and then pulled out. The knife edge is quickly healed and does not leak, and it can be elongated by 20 cm by 1 cm. The deformation capacity is 20 times the original, and the adhesion force is four ...

With the development of heat-resistant powder coatings, there are many applications of silicone resins in heat-resistant powder coatings. So what are the applications of silicone resins in heat-resistant powder coatings? Next, let's introduce relevant knowledge for everyone, let's take a look.With the development of the coating industry, powder coatings have been widely used in the coating of metal substrates. In recent years, the development and application of functional products such as antiba ...

Silicone rubber waterproof coatings are emulsion-type waterproof coatings prepared by mixing silicone rubber emulsion and other high molecular polymer emulsions as the main raw material, mixing appropriate chemical additives and fillers, etc., uniformly mixing. The coating has good permeability, film-forming properties, water resistance, elasticity, adhesion, high and low temperature resistance, etc., and can be used for construction operations on dry or damp bases without clear water.Silicone w ...

Release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when it comes in contact with the chemical components of different resins (especially styrene and amines). The release agent also has heat resistance and stress properties, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the processed part, and does not interfere with painting or other secondary ...
