Headliner Adhesive Applications
Due to the many functions of a headliner, they require the use of a multitude of different materials. This can include composite board, foams, fabrics, plastic and electrical components. Our range of headliner adhesives provides the possibility to combine a wide range of different materials for any headliner application.
The headliner coverstock is the visible layer of the headliner to the passenger inside the car. It consists of several layers of cloth or fabric and foam. Web adhesives bond this layer to a rigid board giving the headliner its unique shape and contours.
Headliner attachment adhesives
Unseen by the passenger, the headliner has many components that are attached to it, providing the in-car comforts of electronic consoles, sunroofs, sound absorption and crash mitigation. Ensuring quality assembly and performance, our headliner attachment adhesives bond these components together securely.
Sound foam and safety plastics
Sound foam reduces the amount of outside noise heard inside the car, while safety plastics help to provide cushioning in case of head impact.
Stiffeners within the multiple functional layers of the headliner attachments support the headliner fabric in the shape of the vehicle.
Wire harness and constole mounting
The wire harness transmits power throughout the vehicle and is an integral part of the headliner attachment. Overhead consoles provide overhead lighting, power for video playback devices and electronics controls.
Automotive headliner adhesive: Smart technologies
We have products in multiple chemistries suitable for lamination of coverstock, edge-folding, and attachment of backside components such as wire harnesses, water hoses, energy absorption foams, safety plastics, hook-and-loop fasteners, and sunroof trim rings and clips.
Our key technologies include:
Hot melt polyolefin
Demonstrating good adhesion to a variety of different automotive substrates, this adhesive type is perfect for bonding safety plastics, acoustic foams and stiffeners.
Hot melt polyamide
Hot melt polyamide possesses excellent plasticiser resistance, making this solution ideal for wires and differing plastics.
Hot melt EVA
Popularly known as expanded rubber or foam rubber, this adhesive has a good cost per part and is used in less critical areas of the headliner such as edge wrapping and clips.
