Ashland Adhesive Bonds BMW Composite Roof

27 January 2006

Ashland Specialty Polymers and Adhesives has helped BMW attach a new light-weight carbon fibre reinforced plastic roof to its M3 CSL vehicle.

The BMW M3 CSL features a roof made of carbon fibre reinforced plastic (CFRP), which is 6kg (13 pounds) lighter than a conventional steel roof. The key to attaching this roof component relied upon a special adhesive to join the roof to the automobile body frame. After testing a number of adhesives, BMW decided that Ashland SP&A’s Pliogrip structural adhesive, a two-component polyurethane adhesive, provided the best solution.

“We’re proud to work with BMW, and to help them bring the M3 CSL to market,” said Hartwig Lohse, Ph.D., European technical manager, transportation for Ashland SP&A group. “Our adhesive technology provided an essential contribution to making this special BMW model a reality.”
