Polyurethane adhesive is an important component of the rapidly developing polyurethane resin. It has excellent properties and has been widely used in many aspects. It is one of the eight important synthetic adhesives.
Polyurethane adhesives have excellent shear strength and impact resistance. They are suitable for various structural bonding fields and have excellent flexibility.
Polyurethane adhesives have excellent rubber properties and can adapt to the adhesion of substrates with different thermal expansion coefficients. They form a soft-hard transition layer between substrates, which not only has strong adhesion, but also has excellent cushioning and shock absorption functions. The properties of polyurethane adhesives at low and ultra-low temperatures are superior to those of all other types of adhesives.
Waterborne polyurethane adhesives have the characteristics of low VOC content, low or no environmental pollution, non-flammability and so on. They are the key development direction of polyurethane adhesives.
The diversity of polyurethane adhesives provides solutions to many bonding problems, especially where other types of adhesives cannot bond or where there are difficulties in bonding.
In addition, polyurethane adhesives have adjustable toughness, simple bonding process, excellent low temperature resistance and excellent stability. It is precisely because of its excellent bonding performance and adaptability to various substrates that polyurethane adhesives have been widely used and become the fastest-growing adhesives at home and abroad in recent years.
