What is a coupling agent? Coupling agent is a class of substances with amphoteric structure, a part of their molecules coupling agent is a class of substances with amphoteric structure, a part of their molecules can be divided into groups and inorganic surface chemical groups reaction, forming chemical bonds; The groups can react with the chemical groups on the inorganic surface to form chemical bonds;Another part of the group has the nature of organic matter. But another part of the group with organic molecules has the nature of organic matter, can react with organic molecules or produce strong intermolecular action, which will be two totally chemical reaction or produce strong intermolecular action, which the nature of the two kinds of disparate materials tightly together, Improve the inorganic filler in the polymer matrix firmly combined with different materials, improve the dispersion of inorganic filler in the polymer matrix, improve the mechanical properties and usability of the polymer material in the dispersion of the polymer material, improve the mechanical properties and serviceability of the polymer material.

Polyurethane sealant is widely used in civil construction, transportation and other industries: Applications in construction - filling and sealing of doors and Windows, glass, etc.; Applications in civil engineering - caulking sealing of expressways, Bridges and airstrips; Automotive applications - Assembly and sealing of Windows (mainly windshield). Polyurethane sealant has many excellent characteristics 1.Strong adhesion, large initial adhesion, wide application range Because a NCO in the molecular chain of polyurethane adhesive can be reflected with a variety of functional groups containing active hydrogen, forming interfacial chemical bond binding, so it has strong adhesion properties to a variety of materials.Not only can bond porous materials, such as foam, ceramics, wood, fabric, etc., but also can bond a variety of metals, inorganic materials, plastics, rubber and leather, etc., is a wide range of application of adhesives. 2. Outstanding low temperature resistance At very low temperatures, the same polymer materials are converted to glass state and become brittle, while polyurethane adhesives can maintain high peel strength even below a 250℃, and their shear strength increases greatly with the decrease of temperature.

Surfactants are a large group of organic compounds, their properties are very characteristic, application is extremely flexible, extensive, has great practical value. Surfactants have been as emulsifier, detergent, wetting agent, penetrating agent, foaming agent, solvent, dispersant, suspending agent, cement water reducing agent, fabric softener, leveling agent, fixing agent, fungicide, catalyst, waterproof, anti-fouling agent, lubricant, acid mist proof, dustproof agent, preservative, spreading agent, thickening agent, furthermore, flotation agent, flow ping agent, oil displacement agent, Anti-caking agent, deodorant, antistatic agent, surface modifier and other dozens of functional reagents are used in daily life and many industrial and agricultural production fields.Surfactant in addition to the large amount of application in the detergent industry and cosmetics industry, also used as additives or additive in food, dairy products, paper, leather, glass, petroleum, chemical fiber, textile, printing and dyeing, paint, medicine, pesticide, film, photographic, electroplating, metal processing, mineral processing, new materials, industrial cleaning, construction and other traditional industries, as well as high and new technology. Although they are often not the main body of the industrial products, but can play a key role in the production of various products. Although its consumption is not large, but can play a key role in increasing product varieties, reducing consumption, saving energy, improving quality and so on. Our company produces various auxiliaries, such as wetting agent, surfactant, welcome to consult

Silicone antifoaming agent is a white viscous emulsion.It has been used in various industrial fields since the 1960s, but large-scale and comprehensive rapid development began in the 1980s.As silicone defoaming agent, its application field is also very wide, more and more attention by all walks of life. In chemical industry, papermaking, paint, food, textile, pharmaceutical and other industrial department of organic silicon defoamer is indispensable in the process of producing a kind of additive, it can not only remove the production process technology bubble on the surface of the dielectric fluid, thus improving filtration, washing, extraction, distillation, evaporation, dehydration, drying process of separation, gasification, such as drainage effect, Ensure the capacity of all kinds of materials and handling containers. Appearance:White thick emulsion Ph:6-8 Water dilution:0.5%-5.0% foaming solution dilution Volatileness:nonvolatile matter Stability:No stratification at 3000 RPM /20 min Ionic properties:Non-ionic Heat resistance properties:No demulsification, no oil bleaching and no stratification at 130℃
