PUR hot-melt adhesives are based on polyurethane. A pur hot melt combines the physical fast setting time of a hotmelt, with a chemical process that improves the structural, durable adhesion of PUR, a widely used base material for adhesives in the building and construction industry
PUR hotmelts react just like standard PUR adhesives, with moisture from the environment. PUR hotmelts are typically "1 component". PUR hotmelts must therefore be provided with an air-tight packaging.
