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 ...

The main ingredients of food-grade defoamers include calcium carbonate\sorbitan fatty acid ester\silicone oil\food preservatives, etc. Of course, there will be a certain amount of short-chain fatty acid defoamers in general defoamers. There are many types of antifoaming agents. Alkyl, polyether, silicon and ether grafts, containing amines, imines and amides, have faster defoaming speed, longer foam suppression time, wider range of applicable media, and even harsh media environments such as high ...

Foamed silica gel is also called addition molding silica gel. It is composed of silica gel and curing agent at a ratio of 1:1. After being vulcanized, it becomes a soft elastic material. It is an environmentally friendly material, the products produced are non-toxic, tasteless, safe and sanitary. Flexible silicone rubber products such as human body, insoles, shoulder pads, patches, non-slip pads, etc. can be made. Tear strength: 55Kn/m; ductility: 100%; temperature range: -40-220℃; fire rating: ...

1 Industry status of methyl high-hydrogen silicone oilMethyl high-hydrogen silicone oil is often referred to as high-hydrogen silicone oil. It is a very important silicone oil product that is very popular at home and abroad. The siloxane main chain in the high-hydrogen silicone oil product contains highly active silicon-hydrogen bonds, which can react with many active groups, and the surface energy of methylsiloxane chain links is low, so its synthetic materials have good properties. Water resis ...
