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 ...
Powdersolid defoamer can be used for metal cleaning agents, electroplating cleaningagents, alkaline degreasing agents, high-grade spray, metal wire drawing fluid,flux, ultrasonic cleaning agent, alkaline degreasing agent, washing detergentbowl, beer bottle cleaning agents, powder cleaning agents, chemical cleaningagents, cutting fluid, industrial cleaning agents, civilian detergents, powdereddetergent, powder detergent, electrolysis water treatment, starch, paper /pulp, textile, printing and dye ...
Recently, researches on defoamers havefocused on the compound of organosilicon compounds and surfactants, thecompound of polyether and organosilicon, the combination of water-soluble oroil-soluble polyether and silicon-containing polyether, etc. Agent, thecompound is one of the development trend of defoamer. At present defoamers,polyether and silicone defoamer performance is the most excellent, these twotypes of defoamer modification and the development of new varieties of researchis also more a ...

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 ...
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 ...
Glass fiber reinforced plastic: Improve thephysical and mechanical strength of the composite wet, wet electricalperformance, and improve the glass fiber cluster, protection and processingtechnology.Adhesives and coatings: Improve the wetadhesion, weatherability, improve pigment dispersion, improve wear resistanceand resin crosslinking.Casting: Improve the strength of resinsand. To achieve a high degree of low gas evolution.Rubber: Improve product mechanicalstrength, wear resistance, wet electric ...
Coupling agent is very common in our liveschemical raw materials. In plastic compounding, the coupling agent is toimprove the synthetic resin and inorganic filler or reinforcing materialinterface properties of a plastic additive, coupling agent, also known assurface modifier. It can reduce the viscosity of synthetic resin melt in theplastic processing, improve the dispersion of filler to improve the processingperformance, thus enabling the products to obtain good surface quality andmechanical, t ...
Curing agent can be divided according touse at room temperature curing agent and heat curing agent. Epoxy resin at hightemperature curing general good performance, but in civil construction in theuse of paint and adhesives due to heating difficulties, need room temperaturecuring. So most of the use of fatty amines, ring lipids and polyamide, and soon. In particular, coatings and adhesives used in winter have to be used incombination with polyisocyanates, or polyhalines having a malodorous odor.A ...
The curing temperature of the curing agentand the heat resistance of the cured product has a great relationship. Similarly,in the same type of curing agent, although the same functional groups, but dueto different chemical structure, its properties and curing properties aredifferent. Therefore, a comprehensive understanding of the same functionalgroups and different chemical structure of the polyamine curing agent of thetraits, characteristics, the choice of curing agent is very important.In ter ...
