PUR Reactive Hot Melt
Moisture-curing polyurethane hot melt with the highest resistance to water, steam and heat once cured.
One-component, moisture-curing PUR hot melts build green strength fast on cooling, then react with ambient and substrate moisture to form an elastomeric, insoluble bond. Fully cured, they resist water, steam, heat and chemicals, giving invisible joints and long life in kitchen and bathroom furniture, profile wrapping and flat lamination. As they contain isocyanate they need moisture-tight packaging and suitable application equipment. Low-monomer (MR) grades without hazard labelling are also available.
