Siloxane oligomers have a series of unique and excellent properties. The thermal stability, impact strength, adhesive strength, lubricity, flame retardancy, solvent resistance, air permeability and leveling property of ordinary polymer materials modified by siloxane oligomers can be improvedLeveling agent is a kind of commonly used coating additives. After coating construction, after flowing and drying, a flat, smooth and uniform coating film is formed gradually. The leveling property of coating ...
After brushing, the treated surface will dry naturally, and the crystal structure of the product will be frozenusage methodTo ensure the best effect, rinse immediately;In winter, if the temperature is too low, immersion, before construction, roller and sealed spray gun can be used for construction;Apply the second coat before the surface is dry; Clean the substrate surface before use.matters needing attention. It can also be used in concrete to restore the transparency of the solution. If there ...
The silicone mold release agent is an "oil-in-water" type silicone oil and water emulsion made by emulsifying and grinding silicone oil. Keep the mold surface lubricated, reduce mold loss, and save mold maintenance and repair costs.advantage1. Silicone mold release agent is a new type of product developed mainly for the mold release of silicone rubber accessories, trademark rubber molds, and silicone keys. It has the characteristics of excellent mold release, smooth product surface, an ...
Silica gel (Silica gel; Silica) Alias: Silicone rubber is a kind of highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2.nH2O. It is insoluble in water and any solvents, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkalis and hydrofluoric acid.According to its properties and components, silica gel can be divided into organic silica gel and inorganic silica gel.Organic silica gel is an organosilicon ...
Add materials 5, 6 and 7 into a clean and dry reaction flask with a stirring and reflux device, and gradually add a mixture of 1, 2, 3, 4 and 8 from the feeding port under stirring to maintain 20-40 The dripping is finished for about 1~1.5h between °C. Then the temperature was raised to 80C, and the ethanol produced in the reaction was evaporated. After most of the ethanol is evaporated, the temperature is raised to 120-130C, connected to a decompression system, the residual ethanol is removed ...
Surfactant Surfactant is a molecule formed by two completely different particles, one particle has a strong lipophilicity, and the other has a strong hydrophilicity. After being dissolved in water, surfactants can reduce the surface tension of water and improve the solubility of organic compounds. A wide range of surfactants (cationic?, anionic?, non-ionic and amphoteric) provide multiple functions for specific applications, including foaming effect, surface modification, cleaning, emulsion ...
The development trend of surfactantsAt present, developed countries have established a complete system for research in the field of surfactants, which can realize the diversification and serialization of product research and development. The development efforts are very strong, and the development concept has broken through the traditional surfactants.Take the application of surfactants in pesticides as an example. Foreign studies on the effect of surfactants on the activity of herbicides have s ...
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, ...
