Structural adhesive
Structural adhesive is a high-strength bonding adhesive used alongside or instead of welding to join modern body panels, especially on bonded aluminium and mixed-material bodies.
What it means
Structural adhesive is a two-part epoxy or polyurethane glue engineered to carry load, not just to hold trim in place. It is applied as a bead along the mating surfaces of two panels, which are then clamped together while the adhesive cures into a continuous bond. Because the bond is spread along the whole joint rather than concentrated at a few points, it distributes stress evenly and resists fatigue and vibration well. Carmakers turned to it as bodies moved towards aluminium and mixed-material construction, where heat from welding can weaken aluminium or warp thin high-strength steel. Adhesive avoids that heat entirely. In practice it is often used together with a small number of welds or rivets in what is called a weld-bond or rivet-bond joint: the mechanical fasteners hold the panel while the adhesive cures, and the cured bond then does most of the structural work. Repairers must follow the carmaker's specified adhesive, bead size, and cure time, because a bonded joint is only as strong as its preparation.
Why it matters in Singapore
More of the cars on Singapore roads now use bonded aluminium or mixed-material bodies, from European marques to newer electric vehicles. When one of these is damaged, a workshop cannot simply weld a panel back on the way it would on an older all-steel car, because the wrong joining method can weaken the structure and compromise how the car protects occupants in a future crash. Using the correct structural adhesive, applied to the carmaker's procedure, is what keeps a repaired car safe and consistent with how it was built, which also matters for insurance assessments here.
How Revol Carz handles this
Revol Carz carries out panel and structural repair at our Toh Guan facility, matching the joining method to how the car was originally built rather than defaulting to one approach. Once the bonded or welded repair is complete, the area is primed and refinished with Spies Hecker paint, computer colour matched, and oven-baked cured in our Italian Saima dust-free booth.
