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 ...
A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.Wetting agent is a surface active agent that can make solid materials more easily wetted by water by reducing its surface energy.Such as sulfonated oils, soaps, pull open powder BX, etc., soy lecithin, mercaptans, hydrazides and mercaptan acetals, etc. c ...
Silane coupling agent is a chemical agent mainly used for glass fiber reinforced plastics. The molecular structure of the silane coupling agent is generally Y-R-Si(OR)3 (where Y is an organic functional group and SiOR is a siloxy group). Siloxy groups are reactive to inorganic substances, and organic functional groups are reactive or compatible to organic substances. Therefore, when the silane coupling agent is between the inorganic and organic interface, a bonding layer of organic matrix-silane ...
Paint defoamers generally include two categories: polydimethylsiloxane and modified polydimethylsiloxane. Polydimethylsiloxane is a high boiling point liquid with poor solubility. Has very low surface tension. Good thermal stability. It is a kind of widely used silicone defoaming agent. With its different structure and polymerization degree, polydimethylsiloxane exhibits different properties. It can be used as a foam stabilizer, defoamer, leveling agent, and hammer pattern. Agent. Only polydimet ...

This forms a special, continuous nano films which can prevent the invasion of all pollutants. Pollutants can be easily clean by water and the gloss can be higher to 90 degrees.Physical Propertiesa) Appearance: White liquid. b) Characteristic: Water BaseGuidanceMust use a special hig ...
In order to reduce costs, improve certain properties of the waterborne polyurethane film-forming material, or combine the performance advantages of two or more polymers, and complement each other, blending or grafting can be used to prepare blends or copolymers.The graft copolymerization of organosilicon and water-based polyurethane adopts a self-emulsifying system to obtain water-based polyurethane-silicone copolymer emulsion. For example, by reacting dimethyldichlorosilane with EO chain-contai ...
For a certain formula system, you should choose the appropriate leveling agent according to the properties of the formula and the desired performance of the leveling agent.1, solvent-based coating system In the primer and middle coat formulations, acrylic leveling agents are usually used. If you need degassing and substrate wettability, you should choose medium molecular weight or high molecular weight acrylic leveling agent. In the primer, if stronger substrate wettability is required, you can ...
