Water based polyurethane resin refers to a binary colloidal system in which a polyurethane resin is dissolved or dispersed in water.Water-based polyurethane resin has the advantages of easy to use, stable performance, strong adhesion, excellent gloss, good heat resistance, etc. It can be suitable for various printing methods, especially suitable for screen printing, plastic packaging and composite...
Development trend of waterborne polyurethane: Nowadays, with the stricter requirements of environmental protection policies, the environmental protection requirements for the performance of adhesives will become higher and higher. Therefore, the greening and environmental protection of composite materials will be more and more important. There will be even more urgency.Therefore, the points mentio...
Precautions for using two-component polyurethane adhesives 1.Before applying the adhesive, the surface of the adherend must be clean, dry and free of grease. 2.The resin and curing agent should be mixed in the required ratio. 3.When scraping the glue, please try to scrape it carefully as it has a defoaming effect. 4.Store adhesive in (> 10, <50 * C) and dry place 5.Run out of the mixed glue ...
Polyurethane and general epoxy products application The use of the two products requires strengthened compressive tensile cement floors or floors and drainage ditches that are resistant to corrosion by strong acids and alkalis, such as chemicals, metallurgical plants, electroplating plants, power plants, pharmaceutical plants, PCB circuit board plants, paper mills, Hardware factory, printing and d...
Glass fiber is an important reinforcing material for the manufacture of fiber reinforced plastics (FRP), and is also used for weaving high temperature resistant fiber cloth.But the glass fiber that has not been treated is brittle, easy to take static electricity after friction, and the surface is smooth, when making the reinforcing material of the resin is not easy to stick with the resin.In the m...
One, extinction principle General can be divided into physical extinction and chemical extinction.Physical matting, is the addition of matting agent, so that the coating in the film when the uneven surface, reduce reflection and achieve low gloss. Two, the kind of matting agent Coating common matting agent can be divided into organic matting agent and inorganic matting agent two categories. 1.Orga...
The choice of solvent In the printing ink manufacturing process, in consideration of the overall solvent system of the ink volatility, to improve the printing ink solvent release and reduce the solvent organic solvent residue, the use of solvents are often several volatile mixed solvents.In the printing ink manufacturing process, the main organic solvents are toluene, butanone, cyclohexanone, ethy...
Anhui Sinograce Chemical Co., Ltd Polyurethane condoms, known as condoms, are made of polyurethane condoms, similar to latex condoms. Polyurethane was applied to condom production in Japan, until the emergence of China's Nakagawa 001, which broke Japan's monopoly on the production field. Because the common latex condoms on the market are thicker and polyurethane has good ...
Solvent selection In the printing ink manufacturing process, considering the overall solvent system of the volatile ladder, improve the printing ink solvent release and reduce printing solvent organic solvent residue, the solvent used is often a mixture of several volatile solvents. In the printing ink manufacturing process, the main organic solvents are toluene butyl ketone cyclohexanone ethyl ac...

Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resi...
From the development of printing industry in developed areas of the future development track can be considered in China's packaging and printing industry to take the road of environmental protection is an inevitable trend, and the environmental protection of ink plays an increasingly important role.Although the stage has not yet established green ink or environmental protection ink discrimination ...
Water-based ink resin is suitable for intaglio printing ink. The ink coating prepared with this product has good film forming ability, quick drying, high gloss, high hardness and scratch resistance, good film forming ability on the surface of paper foil and good compatibility with water-based pigment. Application characteristics 1 Good film formation 2 Suitable for a variety of substrates, good ad...
Acrylic pressure sensitive adhesive is a large range, PUR is one of them, most of the acrylic pressure sensitive adhesive is heated operation, can be reheated after bonding, is reversible.And PUR is wet reaction acrylic pressure sensitive adhesive, heating operation, after bonding and moisture in the air reaction, after the reaction is irreversible (that is, heating will not melt). So PUR is more ...
◆ The procedure of bonding process:◆ The adhesive surface should be evenly coated to ensure infiltration, as far as possible to avoid bubbles, due to the porosity of the adhesive strength greatly reduced, resulting in degumming.Attention should be paid to the alignment of the position, not staggered, can be pressurized, air exclusion, make it close contact. Time is three important parameters of cu...
