Reactive hot melt adhesives are being used in great quantities in all kinds of sectors, starting from industrial, to DIY and Home Décor/Repairs, this is all result of the amazing qualities of HMPUR hot melts that appeal to its users. These adhesives are solid at first and heated before use, being applied while in the molten state. This adhesive is non-toxic and environmentally friendly due to it being solventless.

When the glue cools, a chemical hardening process occurs, which increases its green strength. Water molecules from the substrate or the air then initiate a chemical process that converts the adhesive to an elastomer. Reactive hot melt adhesives create a stronger bond with improved resistance to weather, moisture, heat/flame, and chemicals after full crosslinking which happens in comparatively no time while also being affordable for both bulk and small quantities.

The reactive groups in the adhesive will additionally make strong (covalent) chemical connections with appropriate reactive partners on the substrate's surface, greatly expanding the range of adhesion. These adhesives are also easy in handling due to their low melting temperature. Reactive Hot Melts are of one component reactive type also proving to be useful in melt forming, films, and gaskets.
