It's not just nuts and bolts that hold your car together. It's also products like EFTEC North America's adhesives and sealants that are responsible for bonding together the myriad parts of an automobile. The company and its sister, EFTEC AG, provide sealants, adhesives, and coatings to the auto industry. Other operations include the manufacture of mineral wool, waxes, PVC products, and elastomers. EFTEC North America's customers include Audi, General Motors, and Mercedes-Benz. The two EFTECs existed as a joint venture between EMS-CHEMIE and H.B. Fuller until 2007 when EMS bought out Fuller's portion of the JV.
