Per GM’s guidelines, when an impact-resistant adhesive is removed or damaged, it must always be replaced with an impact-resistant adhesive. If another adhesive is substituted, the vehicle is not considered “returned to pre-accident condition,” which may compromise safety and its ability to be driven. Pliogrip™ 5770 adhesive can be used to meet the repair standard.
The adhesive can be used to bond replacement body panels such as strut towers, frame rails, rocker panels, and body side and rear end panels in place of, or in conjunction with, mechanical means of attachment such as screws or rivets. Professionals should always refer to O.E. replacement procedures for proper attachment methods.
Pliogrip™ 5770 adhesive was also cited in GM’s Repair Insights magazine, which recognized the product’s user friendliness as ideal.
“Ashland’s structural adhesives team is very skilled at helping our customers meet demanding performance standards,” said Tom Stewart, commercial director for structural assembly adhesives, Ashland. “The challenge was in making a product that met all the OEM requirements and is easy for repair professionals to use in all kinds of work environments.”
Using impact-resistant adhesives for structural bonding helps reduce vehicle weights so their organizations can meet federal Corporate Average Fuel Economy (CAFE) standards. They are used in the auto industry to bond dissimilar materials – such as composites and metal – during production. These products are often supplemented with screws, rivets and welds. These adhesives often increase structural durability and improve body stiffness, compared to mechanical means of attachment. The use of epoxies is expanding to include front and rear, upper and lower rail attachments, inner and outer rocker panel joints, and the occupant compartment framing.
