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℃

The difference between water-based gravure printing ink and other printing methods mainly lies in: its printing plate through corrosion or engraving, the formation of a lot of plate surface of different volumes of concave hole, known as the ink hole.The ink hole volume is large, the amount of ink filling in the printing process is large, and the ink layer thickness is transferred to the substrate. The ink hole volume is small, the amount of ink filled in is small, and the ink layer transferred to the substrate is thin, so the orderly and bright and bright picture and text formed on the substrate.In gravure printing, the smooth surface of the non-graphic part that is in contact with the substrate is pressed, and the ink is basically not pressed. The biggest characteristic of gravure printing is that the ink film of the printing product is nearly twice as thick as that of letterpress printing, so the ink layer is full and three-dimensional, but it is prone to sticky failure. Water-based gravure printing ink is characterized by: part of the plate cylinder impregnated rotation in the ink tank, making the entire plate surface is covered with ink, when all the plate with the scraping blade after inking scrape off the plate blank part of the ink, at the same time fully will ink into plate in the recess, and the plate by stamping device within the recesses of ink stamping on the surface of substrates, to complete the transfer of ink to the substrates.Some gravure rotary presses are also installed with a heating and drying device to speed up the drying and curing speed of ink on substrate materials (especially non-absorbent materials). The advantage of water-based gravure printing ink is very outstanding, the printing quality of stereoscopic effect A clear hierarchy Bright color is full Accurate color reproduction, and printing process is relatively simple, lower rejection rate, plate printing endurance than lithographic printing plate printing endurance high, in the field of flexible packaging printing, particularly for food packaging), gravure printing by the people of all ages. Water-based gravure printing inks mostly belong to volatile drying ink, the binder is composed of resin and a large number of volatile solvents, viscosity is very low, the pigment and filler additives and the binder mixture and grinding dispersion into ink.Ink is printed to the substrate, through the solvent quickly volatilized and dry conjunctiva in a gravure printing machine with heating device, the solvent in the ink to accelerate volatilization, drying faster, so can be non-absorbent materials (plastic film, metal foil, etc.) printing.
