Silicone gum is a kind of ointment that solidifies into a tough rubberlike solid material when it comes into contact with moisture in the air. Because it does not flow due to its own weight, it can be......
2021-06-25The use of organosilicone as spray dyeing defoamer has been reported in many literatures. The old dyeing process, the general application of dimethyl polysiloxane defoaming agent, can achieve satisfac......
2021-06-25Polyether modified silicone is a polyether - siloxane copolymer (referred to as silicone ether copolymer) prepared by introducing polyether chain segment into siloxane molecules. Polyether modified si......
2021-06-25Application wide: because of the special chemical structure of silicone oil, it is neither soluble with water or substances containing polar groups, nor with hydrocarbons or organic compounds contai......
2021-06-24Polyether modified silicone is a polyether - siloxane copolymer (referred to as silicone ether copolymer) prepared by introducing polyether chain segment into siloxane molecules. Polyether modified ......
2021-06-24Pure organosilicon, such as dimethyl silicone oil, does not have an antifoaming effect. However, after emulsification, the surface tension decreases rapidly, and the very small amount of it can achi......
2021-06-24General organic compounds such as ethers, hydrocarbons, alcohols and phosphates, the spread coefficient is large, so the bubble breaking effect is very strong, but the bubble inhibition effect is ve......
2021-06-24Silicone defoaming agent is a silicon-containing surfactant as a family of silicone compounds, since the 1960s has been used in various industrial fields, but large-scale and comprehensive rapid dev......
2021-06-24Large-scale commercial application of polysiloxane in industrial coatings appeared in the 1990s, the current use alone is not large. By using polysiloxane with a number of organic monomers and polyme......
2021-06-23Where R represents methyl or ethyl group, and R1 represents organic group, which may be methyl, ethyl, phenyl, sulfhydryl, allyl, amine, epoxy group, etc. When the organic group is methyl, the polysi......
2021-06-23Inorganic: a small amount of organic materials are added to a large number of inorganic substrates and simply embedded in them after mixing; Organic: ordinary coatings containing inorganic pigments......
2021-06-23Why siloxane is not easily destroyed (1) Compared with C-C bond energy of 344.4kJ/mol, Si-O bond energy is equivalent to 270nm ultraviolet light (422.5kJ/mole), ordinary ultraviolet light of 280-340n......
2021-06-231.1 Basic properties of silicon Silicon is one of the most abundant elements in nature, accounting for about 25.7 percent of the mass of the Earth's crust, second only to oxygen. There is no free pur......
2021-06-23(1) Most of the polysilazanes exist in the form of cyclic monomer or oligomer, and the high molecular weight polysilazanes with clear structure lack mature synthesis methods. Therefore, the exploratio......
2021-06-22In terms of coating materials, poly silazane under certain conditions can be converted into silicon dioxide, is a good coating material, has good solubility, excellent adhesion, curing simple, corro......
