FullActive 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.
FullActive Reactive Hot Melt Adhesives Provide the Following Benefits:
Surfaces to be Bonded: Hardboard – Sponge – Glass – Ceramic – Aluminium – Vinyl - PVC – MDF – Hard PVC –Soft PVC – Melamine Paper and excellent bonding for different substrates.
