Reactive hot melt adhesives are heated before processing and applied in molten state. When the adhesive cools down, it builds up its green strength through a physical hardening process. Water molecules (from the substrate or the air) then trigger a chemical reaction which transforms the adhesive into an elastomer. After complete crosslinking, reactive hot melt adhesives provide a stronger bond with a superior resistance against moisture, heat and chemicals.
The reactive groups in the adhesive will also form strong (covalent) chemical bonds with suitable reactive partners on the surface of the substrate, which significantly expands the range of adhesion.
We provides reactive hot melt adhesive based on polyurethane and polyolefin in different supply forms, as well as a new unfilled high-performance PUR adhesive in granulate form – for highest demands regarding quality and appearance.
