What are the advantages of PU adhesives?
PU adhesive is mainly composed of polyurethane and curing agent. It is a kind of adhesive material widely used in industrial manufacturing, home decoration, automobile manufacturing and other fields. Compared with traditional glue and other adhesives, PU adhesives have the following advantages:

What are the precautions of waterborne polyurethane adhesive?
The use of water-based polyurethane adhesive can play a very good bonding effect, but some matters need to be paid attention to in use to ensure quality and safety. The following are several precautions for the correct use of waterborne polyurethane glue:

What are the benefits of waterborne polyurethane adhesive?
Many people use traditional glue when bonding, however, recently water-based polyurethane glue has been widely used in various occasions, what are the benefits? First of all, the adhesion of water-based polyurethane glue is very strong, can bond most materials, such as wood, metal, fabric and so on.

What are the characteristics of waterborne polyurethane adhesive?
Waterborne polyurethane adhesive is a new type of environmental protection adhesive, which has the advantages of strong adhesion, low moisture absorption and no organic solvent. It is widely used in automobile manufacturing, shipbuilding, architectural decoration and furniture manufacturing. So, how does it achieve bonding?

Categories and Characteristics of Waterborne Polyurethane Adhesive
With the progress of science and technology and the increasingly strict requirements of environmental protection laws and regulations, the research and development of environmentally friendly adhesives has been paid more and more attention. Mainly includes waterborne polyurethane adhesive and solvent-free adhesive. Solvent-free glue is generally called hot melt glue. It is composed of thermoplastic resin and does not contain any moisture and solvent. It can flow in the molten state and has adhesive properties after cooling. It can be easily automated. The production process provides high productivity without any Environmental pollution, harmless to humans. In addition, there are emulsion/dispersion adhesives, reactive adhesives and natural polymer adhesives.

What are the performance characteristics of waterborne polyurethane adhesive?
The research of waterborne polyurethane adhesive began in the 1950 s, and it was in the 60 s and 70 s that people really paid attention to. However, the adhesive strength of waterborne polyurethane adhesive at that time was not high, and it was mostly used for packaging adhesive and some occasions with low adhesive strength. In the mid-1970s, water-based polyurethane adhesives used for bonding soles began to appear. Due to poor performance and lack of strict environmental protection regulations, by the end of the 1980 s, they were basically still in the experimental stage. In the early 1990 s, environmental regulations in Europe and the United States became increasingly stringent, and the VOC content of shoe factories began to be controlled.
