Composition analysis and curing attention of polyurethane adhesive
Polyurethane adhesive is a kind of important adhesive products, its high viscosity, good water resistance, cold resistance, high temperature resistance, products are widely used in various fields of automotive, sealing, packaging and many other industries. The weather resistance of polyurethane adhesives used in the automotive field is usually relatively high, so UV absorbers are often added to the product formulation to improve the weather resistanc
Advantages of solvent-free polyurethane adhesive compound
Save energy Solvent-free polyurethane adhesive composite does not require a drying process, can save a lot of energy; Second,
Improve the cooking resistance of solvent-free polyurethane coating adhesive
Polyurethane coating adhesive is widely used in cooking bags. Cooking bags are mainly divided into four types according to the conditions of use: low temperature cooking bag (100℃
Polyurethane adhesive five auxiliaries
In addition to the basic raw materials of isocyanates and polyols, it is also very important to add various auxiliaries in the manufacture of polyurethane adhesives. The auxiliaries can change the production process, improve the adhesive sizing process, improve product quality and expand the application range.
China polyurethane adhesive industry competition
Due to its excellent adhesion properties and adhesion adaptability to a variety of substrates, polyurethane adhesives continue to expand their application fields and become one of the fastest growing adhesive varieties. There is a significant difference in the size of polyurethane adhesive market participants in China. At present, the middle and high-end market is mainly occupied by large and medium-sized enterprise groups at home and abroad, and competitors have considerable production scale. China's polyurethane adhesive industry competition presents
Waterborne polyurethane adhesive
Waterborne polyurethane adhesive is generally used in automotive interior adhesives, flocking glue compound glue, vacuum suction plastic, shoemaking and so on. Among them, automotive interior adhesives, such as automotive interior coating adhesive (door inner panel, instrument panel, armrest), automotive interior ceiling adhesive, automotive interior flocking adhesive (sealing strip flocking), etc. At present, the application proportion of domestic water-based polyurethane in the adhesive industry is low, and the current water-based polyurethane adhesive pro
One/two component moisture cured polyurethane structural adhesive
"Wet curing" means that a single component polyurethane adhesive is cured by using a trace amount of water vapor reaction in the air and reacts with the active group on the surface of the substrate to bond. Structural adhesive refers to a high-performance adhesive that can replace bolts, rivets or welding forms to bond metal, plastic, glass, wood and other structural components and can withstand large loads for a long time. Two-component polyurethane structural adhesives are usually solvent-free two-component polyurethane adhesives. The general curing agent
Polyurethane sealant has high tensile strength, excellent resilience, wear resistance, oil resistance, cold resistance, water resistance, etc., the application field is very wide. Generally used in refrigerated cars, glass curtain walls and other welded joint sealing, automotive maintenance market vehicle windshield, side window glass bonding, bonding between steel and aluminum. The flexible joints of cables, the filling sealing of electronic components, the connection of building materials such as car body joint sealing, glass joint sealing, box body sealin
Universal polyurethane adhesive introduction and application
Universal polyurethane adhesives are generally used for bonding different materials such as metals, plastics, fabrics, especially the composite of polyester film and porous materials in electrical insulation materials, and the composite of packaging decorative materials.
Production status of polyurethane adhesive industry in China
China's polyurethane adhesives started in the 1960s, by the Shanghai synthetic resin Research Institute took the lead in development, at present, the domestic production of polyurethane adhesives there are more than 400 enterprises, of which more than 20 manufacturers above the scale, mainly distributed in the southeast coastal areas. At present, the high-end market of polyurethane adhesives in China is still occupied by multinational chemical giants with scale and technical advantages, such as Germany's Henkel Company (Henkel), the United States DowCorning
Polyurethane adhesive industry characteristics
In recent years, the production scale of polyurethane adhesives in China has gradually expanded, but the product structure is still dominated by low-end products, and the research and development of high-end adhesives will be one of the focuses of development in the next few years. In addition, the production of polyurethane adhesives is facing the impact of national environmental protection and energy saving policies, and it is necessary to improve the production line, and the production growth rate in the next five years may slow down to meet the national
Development status of polyurethane adhesives
Polyurethane adhesives are adhesives that contain carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain. It is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance, wear resistance, the most important is its low temperature resistance, these excellent properties are used in many aspects have been widely used. Polyurethane adhesive was first used in the military field in 1947, by Bayer company triphenylmethane triisocyanate successfully applied to metal and rubber bonding, used on the tank tra
Market size and trend of polyurethane adhesives in China
Polyurethane adhesives have always been one of the most important adhesives in the adhesive industry because of their excellent properties. China's polyurethane adhesive market size exceeded 26 billion yuan, an increase of about 8.8%, accounting for more than 23% of the industry's output value. According to the survey statistics of China Adhesives and Adhesive Tape Industry Association, the development of general and footwear polyurethane adhesives in the traditional market segments is relatively stable, and has maintained stable and low speed growth; Single c
Polyurethane adhesives segment market
There are many subdivisions of polyurethane adhesives in China, which are generally divided into general polyurethane adhesives, polyurethane adhesives for shoes, polyurethane adhesives for composite films, single-component polyurethane foam caulk, single/two-component moisture curable polyurethane structural adhesive, polyurethane sealant, polyurethane hot melt adhesive, waterborne polyurethane adhesive.
Consumption structure of polyurethane adhesives
China's polyurethane adhesive application field is extremely wide, from building materials, shoe industry, packaging, automobiles and other traditional consumer areas to electronic appliances, automotive industry, aerospace, new energy fields and a series of emerging fields. With the slow growth of the real estate sector, the growth rate of rubber used in construction, home improvement, building materials, woodworking and home furnishing industries has slowed down; However, the amount of adhesive used in emerging fields such as new energy vehicles, power bat
the development status and industry characteristics of polyurethane adhesives
Development status of polyurethane adhesives With the continuous advancement of urbanization, information technology and industrialization, domestic investment demand, consumption upgrading demand and ecological environment improvement demand have brought huge growth space for China's polyurethane adhesive market. The rapid development of China's polyurethane adhesive market is mainly related to the continuous development of the domestic economy, as well as the rapid growth of the automobile manufacturing, construction industry and other indus
