Application Description

Adhesives for window profiles

Today, we expect a modern windows or entrance door to last around 25 to 40 years. Within this time, the windows and doors should operate without problems and look good, which means that the laminated foil and the bonding system should not separate from the PVC or aluminum profile, even if the exposure stress due to climate conditions is extreme.

For lamination of window profiles, the PUR hot melt adhesives have proven for decades now to be highly suitable. Continuous further development of the foils used, the steadily increasing variety of materials and decors, and also the reduced storage time for the profiles after lamination – all of these factors represent more challenges for the adhesives. This is why today, we need adhesives that adhere to a multitude of different materials with fast crosslinking, which allows immediate downline processing of the laminated profiles.

Primer

The primer has two major purposes:

1. Cleaning the profile surface by dissolving of usually non-polar foreign matter on the surface, resulting from the PVC formulation or developed during extrusion.

2. Improving the physical adhesion on the profile surface by swelling/slight dissolving and / or by modifying the surface polarity to enhance adhesion.
