3M Impact Resistant Structural Adhesive3M Impact Resistant Structural Adhesive is formulated for demanding automotive OEM-specified structural bonding applications. It’s excellent for collision absorption in steel structures and advanced lightweight aluminium alloys. This two-part epoxy adhesive delivers extended worktimes – up to 1 hour – and can be rapidly heat-cured which takes approximately 30 minutes at 80°C. The adhesive also changes from silver to purple as the adhesive cures. DetailsDesigned for Structural Collision RepairThis adhesive formula targets collision absorption in demanding OEM-specified structural bonding applications.Strong Bonds on Mixed MetalsIt bonds both steel and automotive aluminium, making it ideal for modern, lightweight vehicle structures.Immediate Mechanical FixationYou can weld-bond or rivet-bond the adhesive immediately after application, saving valuable time.Extended Work TimeYou get up to one hour of work time, allowing precise part alignment and fit-up.Fast Heat CureHeat curing accelerates the process, reaching full cure in approximately 30 minutes.Visual Cure IndicatorThe silver adhesive turns purple as it cures, providing a clear visual indication that bonding has begun.Withstands Harsh ConditionsIt performs reliably under extreme temperatures, maintaining bond integrity in demanding environments.Corrosion ProtectionIts corrosion-inhibiting formula helps protect metal components over the long term.
