viscosity of the adhesive, the optimum temperature for melting and processing of the new PUR hot melt is about 120 °C. Plastic foils are therefore exposed to [...] to wider variations in the surface tension of decor materials. The new PUR hot melt represents a consequent improvement and complement of tested and proven adhesives [...] pressing zones or pressing times. Due to the broader range of adhesion, the PUR hot melt provides an optimum adhesion to substrates such as PVC and aluminium profiles
