Common high temperature resistant glues can be divided into organic high temperature resistant glues and inorganic high temperature resistant glues according to their properties.1. Common organic high temperature resistant glue:The common temperature resistance of the common high-temperature glue is limited to below 400℃, and it mainly includes silicone glue, phenolic resin glue, urea-formaldehyde resin glue, temperature-resistant epoxy glue, polyimide glue, etc. This type of glue can be soft a ...

Silicone elastomers are cross-linked gel polymers dispersed in a siloxane or hydrocarbon carrier. Since its first launch in the personal care industry, its excellent performance has had an important impact on color cosmetics, antiperspirants and skin care products. Typical applications include thickening, oil/sebum absorption, oil control, skin feel improvement and the production of water-in-oil emulsions.They are usually made by reacting polyhydromethylsiloxane and a crosslinking agent (usually ...

The current theories about foam formation differ between defoaming and defoaming. The function of defoamer is to trap air at the interface. The function of the defoaming agent is to make the tiny air (microbubbles) dispersed in the coating film quickly rise to the surface after the coating process and the coating film are completed. However, it is often impossible to make this distinction clearly in practical applications. Antifoaming agents can also eliminate microfoam to some extent. The defoa ...

Silicone epoxy resin is made by condensation of low molecular weight polymethylphenylsiloxane and bisphenol A epoxy resin in the presence of a catalyst.Light yellow to yellow uniform liquid, epoxy value 0.01～0.03mol/100g, solid content 50%. Viscosity (coating 4 cups, 25℃)≤30s. There are also solid organic silicon epoxy resins, yellow to brown solid, with a softening point of 60-80°C. The epoxy value is 0.25～0.35mol/100g. The epoxy resin adhesive is formulated with silicone epoxy resin, whic ...

In recent years, the amount used has doubled. Among them, the amount of aminosilicone emulsion is the largest. For different styles of feel, such as resilience, waxiness, etc., modified silicone oils with other groups need to be developed . As a new type of organic silicon functional polymer compound, epoxy modified silicone oil has been widely concerned and used due to its own reactivity and high adsorption properties. The traditional preparation methods include: ①Prepared by emulsion polymeri ...

Silicone surfactants are a type of surfactant composed of polydimethylsiloxane as its hydrophobic backbone and one or more organic silicon polar groups connected to the meta or terminal positions. According to the chemical properties of the hydrophilic group R in its chemical structure, silicone surfactants can be divided into four categories: anionic, cationic, nonionic, and zwitterionic. Among them, nonionic surfactants are the most studied. , The most widely used.1. Cationic silicone surfacta ...

Silicone oil r is CH3, OH; R´, is CH3, H, etc. The oil content is generally 20% to 30%. The pH value is 6～8. Centrifugal stability (3000r/min) 15-30min. The surface tension is small, and the contact angle to water is large. Heat and oxidation resistance. It is prepared by emulsion polymerization of octamethylcyclotetrasiloxane in the presence of anionic surfactants such as sodium dodecyl sulfonate or cationic surfactants such as cetyltrimethylammonium bromide and a catalyst . It is a ...

Price Adjustment Notice Dear customers:First of all, thank you very much for your long-term support and trust in our company!Recently, the price of a variety of chemical raw materials has risen sharply for several consecutive times, which has had a serious impact on our production costs. Based on the principle of honest operation and win-win cooperation, the company has determined that since September 1, 2021, the various types of silicone oil sold by our company will increase by 10-20% on ...

Product characteristics Lubricating oil defoamerLubricating oil defoamer is a special defoamer developed by introducing foreign technology and equipment according to the characteristics of machining fluids. It is mainly suitable for the defoaming of high temperature, strong alkali and high viscosity systems. The special defoamer for lubricating oil also overcomes the shortcomings of the incompatibility of general defoamers and emulsified oil, can be mixed with various lubricating fluids, and doe ...
