Auto Repair Industry Society (SCRS) Releases Video on Adhesives in Auto Manufacture and Repair

Posted By ASC, Wednesday, February 8, 2017

The Society of Collision Repair Specialists has released an educational video series to help auto repairers adapt to the increasing importance of adhesives in auto manufacture and repair. The Society says it will be posting more YouTube videos during the course of 2017. In an interview with an auto repairers’ news publication a Society spokesperson warned that incorrect handling of repairs could lead to the voiding of guarantees, and that this could lead to the payment of damages that could cost as much as a new luxury car.

Although the organization rates the use of structural adhesives as “easy,” it suggests that repairers conduct “dry runs” with vehicle components that must be bonded before applying the adhesive and going ahead with the procedure. The manufacturer provides time limits for the process, and repairers must ensure they can apply adhesives and bond components to specification.


Workshops will have to allocate curing areas that will allow parts joined with adhesives to be left undisturbed during the curing process. Ideally, this should be a low-traffic area where the components are less likely to be disturbed. Technicians must be aware of the need to leave parts alone during curing and will need to be familiar with issues such as required personal protective equipment (PPE) and curing temperatures.


Extra caution must be exercised when welding components backed with adhesives or foams. Adhesive bonds may break at very high temperatures, and foams could ignite. An auto repairer commented that he had seen many cases in which adhesive bonds have been broken owing to excessive heat exposure during repair.


OEMs will also specify what surface preparation techniques are required to ensure bond integrity. Sometimes, e-coat should be removed prior to bonding, for example. Each OEM and brand has its own requirements, and repairers will need to be familiar with the specific adhesives and procedures applicable.


Cutting costs by choosing cheaper adhesives is not a viable option. For example, the lower-cost adhesives may not have the required bond line thickness. All in all, it’s wisest to avoid substitutions. The specified materials have been developed and tested for vehicle safety, and the OEMs have also examined how repairs will hold up when subjected to impacts.
