Polyurethane adhesives: types, properties and uses

Polyurethane (PU) adhesives combine flexibility with high strength. We compare 1K, 2K, PUR hot melt, PU dispersion and solvent-based PU adhesives.

Dieser Artikel ist derzeit nur auf Englisch verfügbar.

Polyurethane adhesives are based on isocyanate/polyol chemistry and form flexible yet strong bonds on wood, metal, plastics, foams and textiles, tolerating impact, vibration and temperature changes.

Types

1K moisture-curing PU (assembly, panels), 2K PU (composites, vehicles, doors and windows), PUR reactive hot melt (edge banding, wrapping, lamination), PU dispersion (3D membrane pressing), solvent-based PU (PVC, leather) and PU sealants/foams.

Notes

Reactive PU contains isocyanates — follow health and safety rules. Moisture-curing products cure slowly in closed joints; use 2K there. For isocyanate-free options see MS/hybrid polymers.

See reactive 1K/2K systems, reactive hot melts and PU foams.
