A New Option for Automotive Interior Trim Assembly

Posted on 10/27/2015 8:43:56 AM By ASC

Assembling automotive interior trim is a complex process. The components are made of a variety of different materials, some of which are notoriously resistant to adhesives. The adhesives themselves need to be applied cleanly, efficiently and cost effectively, and worker safety is a significant concern. And, the finished assemblies have to withstand rough handling and temperature extremes for the life of the automobile. Until now, meeting all of these demands with a single adhesive has been impossible, requiring compromise in selecting individual  adhesives and, in most cases, requiring multiple production lines to handle different adhesives depending on the substrate. H.B. Fuller's Swift®lock 2900, a new polyurethane reactive hot melt (PUR-HM), meets all of the performance requirements regardless of substrate. It adheres to both Acrylonitrile-Butadiene-Styrene (ABS) and Polypropylene (PP) substrates without any kind of pretreatment, eliminating the need for multiple production lines. It is suitable for spraying, as well as for slot die and roll coating applications. It has very low VOC content. It sets quickly, speeding up throughput on the production line, and it matches or exceeds the performance of currently used polyolefin reactive hot melts (PORs).
