Reactive hot melts are single-component adhesives that are applied in the molten form (like conventional hot-melt adhesives) but have an additional secondary cure with atmospheric moisture to give a crosslinked polymer. Reactive hot melts will give almost instant fixture strength as the hot melt solidifies and over the next few days will increase in strength as the secondary cure urethane element is completed.

The reactive hot melts bond well to many substrates, and have good high-temperature performance and considerably improved cold flexibility over conventional hot melts. They also have excellent water and vapour resistance and improved solvent resistance and are used for major structural applications such as the assembly of large panels in insulated garage doors and for the lamination of PVC sections in window construction.
