Bus and coach operators expect high levels of durability from their vehicles. Resistance to impact, extreme temperature conditions and round the clock operation make extreme demands on all areas of the vehicle. Sika has formulated a range of elastic bonding solutions for floor and side panel assembly to enable vehicle manufacturers to satisfy these challenging demands. Sikaflex provides high-performance elastic assembly within an easy-to-use one-component formulation. Sikaflex hybrid technology provides the high performance of Sikaflex polyurethane systems combined with reduced substrate preparation and improved ecological benefits. Sikaflex-254 Booster provides the high-performance attributes of Sikaflex, combined with rapid full cure due to the combination with Sika’s proprietary Booster system. SikaForce two-component polyurethane combines high strength with good flexibility. SikaFast two-component methyl methacrylate and ADP (Acrylic Double Performance) structural adhesives provide high strength and excellent impact resistance with low surface preparation. SikaPower body shop structural adhesives and sealants are heat-curing products based on one- and two-component PUR-epoxy hybrid technology.

| Why Use Adhesives? | | |
| |
|
|
|
| - |
|
Bonded assemblies are better able to withstand shock and impact, minimising repair costs and frequency |
|
| - |
|
Use of adhesives and sealants does not damage the vehicle corrosion protection layer, therefore reducing the likelihood of repair |
|
| - |
|
Adhesive systems absorb vibration, improving interior and exterior vehicle noise levels |
|
| - |
|
Bonding shows aesthetic and process advantages against mechanical fixing methods |
|
