SikaPower® adhesives are one-component, epoxy based, bulk hybrids which are cured by the temperature influence of electro-coat ovens. The SikaPower® product portfolio includes crash durable, structural and e-coatable adhesives. All SikaPower® adhesives are available with or without glass spheres, which are important to keep a required bond line distance between two metal sheets and to control the gaps.
The bonding of oily substrates (standard anti-corrosion treatment and deep drawing oils, approx. 3 g/m2) is possible because of the oil uptake during the heat curing process; This is an essential material behavior for good adhesion to substrates. Common substrates in body shop applications for SikaPower® adhesives include all types of steel, aluminum and carbon fiber reinforced plastics (CFRP), and combinations of these substrates, in mixed material bonding.
SikaPower® adhesives are delivered as bulk material and applied by cold or warm pumping equipment. In most cases, the last part of the dispensing system pipes, especially between doser and nozzle, is pre-heated in order to ensure the same application properties over all climate seasons. Applications are preferably done automatically by robot but in some cases manual application is implemented as well.
SikaPower® - Crash and Structural Repair
OE-Quality Bonding for the Repair Shop
Lighter weight construction, greater use of mixed materials and higher safety standards have become important drivers in vehicle design, all of which have forced manufacturers to re-think their production processes.
Body shop joining for example, has evolved from purely mechanical joining to more hybrid joining processes (like bonding with mechanical fixation) and as a result, our versatile, one-component SikaPower® adhesives have become go-to solutions for new vehicle production.
Meeting the same quality expectations in the repair shop creates additional challenges, because the same production and curing processes, controlled conditions and specialized equipment (like cataplasma ovens), can’t be transferred to the repair garage.
Utilizing extensive expertise with both two-component (2C) epoxy adhesives and one-component SikaPower® adhesives, our engineers have developed a new generation of 2C epoxy-based adhesives specifically for repair applications. These OEM-approved adhesives allow technicians to repair vehicles to OEM standards for safety, quality and life-cycle performance. They can also reduce the steps associated with traditional joining processes. As example, spot welding - or riveting can be used which reduces marking, as well as the need to disassemble the interior and fuel system.
