With vehicle manufacturers relying all the more heavily on adhesives in vehicle assembly, repairers also need to get up to date on the latest adhesives as well as when and where to use them. General Motors says that adhesives are ‘central’ to vehicle manufacture and repair since 2015, and is providing training and advice to repairers.
It stresses the importance of contacting OEMs to find out about the right adhesives to use when performing structural repairs, since the stiffer chassis made with the help of adhesives improves the ride experience and reduces noise. Specialized adhesives can’t be replaced with any old ‘glue’ or standard body filler, and applying welds to materials such as ultra-high strength steel compromises the strength of the material. To repair a car so that it’s literally ‘as good as new’ repairers need to be informed about the right adhesives to use.
3M suggests that giving repairers the cue to find out about the correct adhesives could be as simple as color coding the adhesives used during auto manufacture. For example, if an adhesive appears silver during application, that’s relatively standard, but if the adhesive cures to a purple or red color, repairers will know that they’re looking at a specialized adhesive. That’s how 3M is making its 7333 adhesive distinctive.
Other impact-resistant adhesives that repairers will need to look out for include Ashland Pliogrip 5770 and LORD Fusor 2098. When repairing a car, no substitutions can be made. If this happens, safety as well as drive experience may be negatively affected. And although these adhesives have seen the widest useso far since 2015, they’re still present in older cars. A 2012, 2013 or 2014 model, for example, could also require a knowledge of adhesives for a safe and effective repair.
