Thermoplastic Adhesive Films for Automotive Interior Trim Applications

1991-02-01

Joining dissimilar parts in automotive interior trim applications has been accomplished by utilizing mechanical fasteners, organic and water based adhesives, and more recently, thermoplastic polymers. Recent trends towards reducing solvent emissions and waste management problems, improving the consistency of adhesive application, integrating parts, lowering parts fabrication costs, and designing a specified bond level has increased the use of thermoplastic adhesive films as bonding agents in several applications. Initial efforts began over fifteen years ago with Dow Adhesive Films (DAF) being designed for bonding interior trim fabrics to various substrates. Films have subsequently been designed to improve performance of many interior trim parts in many ways such as: improving water resistance, allowing the part to be molded before installation, imparting a slip surface to a part, and supporting a non-woven fabric.

Design and Application of Thermoplastic Adhesive Films for Headliner Composites

1991-02-01

The construction of most automotive interior headliners requires an adhesive material to bond polyurethane foam-backed fabric to a molded headliner shell. More than ten years ago, The Dow Chemical Company qualified and began supplying a thermoplastic adhesive polymer film for headliner applications which replaced wet adhesive systems at several fabricators. DAF 899 adhesive film has gained acceptance in the industry due to excellent performance, convenience, and cost effectiveness without additional waste handling or volatile organic emission concerns. Recent advancements in headliner design such as additional recessed areas with more demanding contours, new substrate materials and the desire for more efficient operations created an opportunity to design improved adhesive films to meet the emerging industry demands.
