Silicone resin is a highly cross-linked polyorganosiloxane with a network structure, usually methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylbenzene Various mixtures of dichlorosilanes, in the presence of organic solvents such as toluene, are hydrolyzed at lower temperatures to obtain acid hydrolysates. The initial product of the hydrolysis is a mixture of cyclic, linear and cross-linked polymers, usually containing a considerable number of h ...

Silicone polymer-silicone resin, silicone rubber, silicone oilMade from basic raw materials. OrganicThere are two main types of silicone resin paint, one type is low molecularSilicone-based silicone resin paint, the other type is modifiedSilicone resin paint.Silicone resin paint has heat resistance, weather resistance,Ozone resistance and resistance to ultraviolet rays in sunlight, its gloss retention and resistanceThe pigment has good powdering properties and excellent electrical insulation. It ...

In the formulation, the main functions of surfactants are: one is to improve the emulsifying ability between the components, so that they can be more effectively mixed with each other; the other is to control the system to have proper surface tension during the foaming process to produce good Bubble network structure, therefore, can also be called foam stabilizer. Polyester and polyether flexible foam have different raw material bases and different properties. Therefore, the selection and dosage ...

General resin refers to an organic structure that can soften or flow after heating, and is mostly semi-solid and solid at room temperature. Broadly speaking, resin can refer to all macromolecules processed by plastics, especially chemicals. Resin itself is also one of the raw materials for manufacturing plastics. It can be said that the application of resin is very wide. The silicone resin mentioned by the editor here refers to a very special kind of resin, also called a highly cross-linked mixt ...

For non-chemical professionals, this term is too unfamiliar. Will it exist in our lives and is closely related to life? The stickers, label paper, and even the adhesive part behind the aunt’s towel in our homes are all Cannot do without "silicone release agent". Now, the silicone manufacturer Xin Jiayi will take you to understand what a silicone release agent is.Release agent, also known as release agent, is used between the substrate and the pressure-sensitive adhesive layer. Its mai ...

With the rapid development of industry in our country, the use of defoamers has become more and more widespread, but many people only know that defoamers are mainly used to eliminate foam, but have not deeply understood the working principle of defoamers. Today I will introduce to you the working principle of defoamer.One, defoamer ingredientsWe all know that to understand the working principle of a product, we must first know the composition or structure of the product. First, let's take a look ...

Silica sol is a colloidal solution, odorless and non-toxic. Silica sol is a dispersion of nano-scale silica particles in water or solvent. Since the SiO2 in the silica sol contains a large amount of water and hydroxyl groups, the silica sol can also be expressed as SiO2.nH2O.Silica sol inorganic polymer coatings have been developed in recent years. The key technology for preparing the coating isSilica solUse a special method to remove the water-soluble sodium ions in the water glass. Generally, ...

Silicone rubber waterproof coatings are emulsion-type waterproof coatings prepared by mixing silicone rubber emulsions and other high molecular polymer emulsions as the main raw materials, mixing appropriate chemical additives and fillers, etc., and uniformly mixing them. 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 wet bases without clear water. ...

There is no unified understanding of the mechanism of defoaming agents. According to the mechanism of defoaming agents proposed by the predecessors, there are roughly the following:A general defoaming mechanismTypical general defoaming mechanisms are Robinson defoaming mechanism and Ross hypothesis. The Robinson mechanism is the basis of the Ross hypothesis. It mainly emphasizes the drainage of defoamers to destroy the foam and the Marangoni effect to achieve defoaming; the Ross hypothesis is ca ...

Silica gel can be used as a desiccant and can be reused. Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel mSiO2·nH2O. It has an open porous structure with a large specific surface (surface area per unit mass) and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and reused. Add acid to the alkali metal silicate (such ...
