The relationship between PUR adhesive and hot melt adhesive Hot-melt adhesives are a large category, and PUR is just one of them. Most hot-melt adhesives are heated and can be reheated after bonding. It is reversible, and PUR is a moisture-reactive hot-melt adhesive. After heating, it will react with the moisture in the air after bonding, and it will be irreversible after the reaction (that is, it will not melt when heated). Therefore, PUR is more resistant to high and low temperatures....

(B) Adhesive hot melt glue Binding is the binding of the cover and the inner album (the book block). The processing of paper between two monomers with similar or identical polarity can be seen as a purely physical behavior, unlike plastic film, which is the result of comprehensive physical and chemical behavior. The physical behavior of glue binding is the republic of the second movement. The first time is the application of glue. The second time is the cover. 1. Glue-glue hot melt adhesives...
Henkel innovation breakthrough Polyurethane adhesives have been awarded for the first time by German Lloyd's Classification Society for blade bonding technology In wind turbines, the blade tip rotates at speeds of up to 300 km/h and resists the huge pressure load. The quality of the moving blades undoubtedly depends on the quality of the adhesive. A few days ago, German Lloyd's Register issued the first polyurethane adhesive certification in the field of wind energy. The honor is awarded by...
Hot melt glue is a green and renewable industrial adhesive. Is this true? Adhesives are also environmentally friendly? Is it green? Many customers will ask such questions when negotiating with our hot melt adhesive manufacturers. in fact. It is normal for customers to have such questions. Because, in people's subconscious, adhesives are toxic, and hot melt adhesives are naturally toxic because they are adhesives. However, there are many differences between hot melt adhesives and other...
Question one, polyurethane adhesive and epoxy adhesive which is less toxic? Polyurethane adhesive raw materials and epoxy resin adhesive materials are toxic. For example, polyurethane curing agents are mostly isocyanates, which have high activity and are harmful to people's kidneys. The organic tin in the catalyst is a poisonous or highly toxic chemical raw material. The epoxy curing agent amine curing agent is also toxic, reactive diluents are toxic or highly toxic chemical raw materials....
Prior to utilizing the jigsaw glue for wood slabs, the wood is aged at least you month. Many wood processing manufacturers often ask us why it is necessary to dry the wood for a time period before using the jigsaw stuff for wood jigsaw. If the full time is insufficient, the goods following the woodworking rubber panels are prone to cracking. As an expert woodworking rubber manufacturer, Jincheng adhesive, that has 16 many years of experience in woodworking silicone production and development,...
I. Introduction: We. Introduction: The availabilitymonetary crisis problems has seriously impacted China 's wooden- based panel industry, and it has additionally brought unparalleled affect manufacturing in urea- formaldehyde resin stuff. Where is just how away? The only path out-- only keep costs down! It will always be of huge significance to help make new urea- formaldehyde botanical adhesives to lessen cost chemicals. Second, the functions: The clean urea- formaldehyde resin cement adhesive...
With the introduction of social economy, the flexible packaging industry has also developed rapidly. With the improvement of living standards, people are more and more uneasy about food safety and health. Almost all plastic packaging products are used for food display, so the safety and environmental protection issues of plastic display are closely related to the health of consumers. At present, the food packaging composite film in China is simply composited with solvent-based glue to ensure...
