Hot-melt adhesives are solvent-free or water-free products that are more or less solid at room temperature, are present in the hot state as a viscous liquid and are applied to the adhesive surface. On cooling, they solidify reversibly and form a firm bond. This group of adhesives are thermoplastic polymers based on different chemical raw materials<\/p>\n\n\n\n

What is a hot melt adhesive? <\/p>\n<\/div>\n\n\n\n

Thermoplastic and curing hot melt adhesives<\/h2>\n\n\n\n

Hotmelt adhesives can be divided into physically and chemically setting adhesives. The physically setting adhesives are thermoplastics, the chemically setting ones form thermosets, i.e. three-dimensional networks. Another type of classification is regarding the solidification mechanism. Here, hotmelt adhesives are divided into amorphous polymers, semi-crystalline polymers, and high-molecular polymers, the first two having a glass transition temperature above room temperature and the latter having a glass transition temperature below room temperature <\/p>\n\n\n\n
