The chemical state of polydimethylsiloxane -- 2017-01-17

Polydimethylsiloxane chemical stateDimethyl silicone oil, colorless or light yellow liquid, odorless, hightransparency, with heat resistance, cold resistance, viscosity with temperaturechange is small, waterproof, surface tension is small, with thermalconductivity, thermal conductivity of 0.134-0.159W / M * K, light transmittanceof 100%, dimethyl Silicone oil non-toxic and tasteless, with physiologicalinertia, good chemical stability. Electrical insulation and weatherability,hydrophobic, and has ...

Polysiloxane -- 2017-01-16

There are few silicone-free compounds inthe new cosmetic formulations, and the use of silicone compounds in personalcare products has achieved significant growth. In addition, even with the mostadvanced technology of the formulator, still inevitably use siloxane.Silicone polymers consist of differenttypes of compounds, including conventional silicone oils, water-solublepolymers, oil-soluble polymers, fluorine-soluble polymers, and polymers withvarious solubility. They exist in a variety of forms ...

Siloxane esters -- 2017-01-13

The final action to be considered is thederivatizing reaction. In this step, the reaction group added to the functionalaction step is further reacted to give a new compound, and the reaction of thehydroxyl group with the polydimethylsiloxane copolymer polyol is an example ofsuch a reaction. In fact, a series of surface-active siloxanes, comparable to alarge number of standard surfactants, have been developed and marketed.Silicone esters are an excellent example of the effect of derivatization on ...

Surface Tension -- 2017-01-11

Surface tension is the main driving forceof coating leveling, but the surface tension difference, but it is the maincause of surface defects. To improve the surface tension of the coating toachieve the surface tension balance, which is the flow of the coating andleveling is very useful, but it can’t. So people had no choice but to reducethe surface tension of the coating to eliminate surface tension difference,control the surface state of the coating to eliminate surface defects. Such asthe eli ...

Performance, a wide range of applications of defoamers -- 2017-01-04

Polysiloxane defoamer with defoamingrapidly, anti-foam for a long time and safe non-toxic and so on. But it isinsoluble in water, high temperature, alkali resistance is poor, polyetherdefoamer high temperature, strong alkali resistance, but its defoaming speedand suppression bubble time are not ideal The polyether chain is grafted intothe polysiloxane chain through the condensation technology, which has theadvantage of the second kind of antifoaming agent, and becomes a defoamingagent with excel ...

Polymer composites additives -- 2017-01-03

Coupling agent is an important, widely usedin the field of treatment agent, mainly for polymer composites additives. Themost important characteristic of the molecular structure of the coupling agentis that the molecule contains two groups with different chemical properties.One is a group of pro-inorganic, easily with the inorganic surface of thechemical reaction; the other is the pro-organic groups, and synthetic resin orother polymer chemical reaction or hydrogen bond dissolved in them. So thec ...
