HMPUR adhesives of the Exterior range are mainly used for the lamination of PVC and aluminium substrates in the window sector with special decors that will come into direct contact with the exterior.

They must therefore have excellent resistance to weathering such as water, humidity and high temperature fluctuations.

These HMPUR glues are supplied in a solid state to be melted and applied with special slot nozzle or heated roller system. Once applied, the reactive polyurethanes guarantee an initial bonding of a physical nature. As it cools down, the first bonding stage will take place, followed by the last one, the chemical one, where the adhesive will provide a solid and lasting bond between the substrate and the laminate.

The HmPur adhesive not only guarantees excellent adhesion, but thanks to its nature it acts as a barrier against elements that could damage the material over time.
