Research progress of hot melt pressure sensitive adhesive
The research progress of SIS-based hot melt pressure sensitive adhesive and polyurethane hot melt pressure sensitive adhesive at home and abroad was reviewed in this study.The advantages and disadvantages,modification methods(such as polymerization modification,physical blending modification,chemical modification),and research and application fields(such as metal bonding,logistics labels,building waterproofing materials,and medical adhesives)of both were elaborated,and the future development directions of SIS-based hot melt pressure sensitive adhesive and polyurethane hot melt pressure sensitive adhesive were also discussed.
