Vehicle interior lamination

Adhesives play a major role in the manufacture and assembly of the different parts for car interiors. Whether tried and proven for many years or tailored to specific applications, Jowat supplies the suitable adhesive solution for all current requirements and process parameters in all established bonding methods.

A particularly demanding application is the lamination of instrument panels, side and door panelling, and centre consoles with a wide variety of different decor materials. Jowat provides a broad spectrum of suitable bonding solutions with highest heat resistances, which reaches far beyond the standard applications, such as press laminating and vacuum deep-drawing.

PO hot melts facilitate the lamination of polypropylene form parts in IMG processes without pretreatment and provide a fully recyclable compound. Powerful PUR hot melts are ideal in all laminating procedures for the entire vehicle interior. And for the top league of lamination, for instance the real leather lamination of instrument panels and door panelling with visible seams, Jowat supplies PU dispersions which have been optimised specially for these mostly manual assemblies.

More frequently thin and porous textiles are used to cover A-B-C columns, parcel shelves or ceilings. These applications are exposed to direct sunlight and are therefore laminated with highly UV-stable PU dispersions. Even after many years of exposure, the bondline will remain invisible due to the excellent oxidation resistance and colour stability of these adhesives.

Jowat adhesives for car interiors support the efficiency of modern manufacturing processes with regard to all lamination methods, including VACFLOW – short process cycles, low energy consumption, and clean processing – as well as the specific requirements of the different parts. Our product range provides for each application suitable products with a broad spectrum of different initial strengths and activation temperatures, edgefolding capability, heat and UV resistances, as well as precoatings with good storage stability for products supplied on reels.
