Application Description

Lamination applications in the manufacture of window profiles are characterised by a growing diversity of substrates and decor materials, further developed foil types, higher fluctuations in surface tension, and increasing feed speeds. These challenges can only be mastered with suitable adhesive products.
Jowat has expanded its portfolio of tried and proven bonding systems for wrapping window profiles and developed a new generation of adhesive systems consisting of powerful PUR hot melts and primers.

The new high-performance adhesives are characterised by significantly improved properties, such as a wider range of adhesion for optimum adhesion to PVC and aluminium, and a higher green strength. The latter facilitates an increased laminating speed while maintaining process stability and providing a reliable bonding of window profiles and new, more rigid foils with higher restoring forces – even in applications with shorter pressing zones. In addition, the new hot melt adhesive also has a lower viscosity, which means it can be processed at lower temperatures, therefore facilitating shorter production cycles and a reduced thermal exposure of the thermoplastic foils to be laminated. The hot melt adhesives are certified according to RAL-GZ 716 for use in combination with conventional primers as well as with new VOC-reduced, NEP-free primers that are not subject to hazardous labelling restrictions.

The excellent process stability and outstanding processing characteristics due to the optimum interaction between the new powerful adhesives and the latest generation of Jowat primers provide great benefits in window profile wrapping applications. For instance, the crosslinking of the PUR hot melts is accelerated when the primer components come into contact with the adhesive, facilitating a downline processing of the laminated window profiles after just 24 hours and representing a major contribution towards more efficient lamination processes.
