Bus and Coach
Systems: Bus and Coach
Bus and coach manufacturers utilizes a wide range of materials and processes in the assembly of the body structure. Sika provides a range of material technologies ideally suited to these challenging and diverse environments. Sika’s sealants and adhesives are easy to combine with other joining technologies. Flexibility, durability and a reduction in the number of spot welding points are just some of the advantages provided by sealing and bonding technology.
Sikaflex sealing materials are easy-to-use one-component formulations and provide good tooling properties. SikaPower body shop adhesives and sealants are heat-curing products based on one- and two-component PUR-epoxy hybrid technology. SikaPower suit the requirements of applications as diverse as anti-flutter, hem flange, stiff structural bonding and crash-resistant spot weld applications.
Floor, Side Panels and Luggage Doors Adhesives
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 provide 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. SikaFast two-component methyl methacrylate and ADP (Acrylic Double Performance) structural adhesives provide high strength and excellent impact resistance with low surface preparation.
Bus and coach manufacturers face particularly tough challenges for construction of roof assemblies for modern bus and coach vehicles. Apart from obvious requirements for long-term durability and resistance to harsh climates, additional requirements include lowest possible weight (vehicle handling and fuel economy), highest possible strength (roll-over resistance for occupant safety) and increased functional complexity (air conditioning units, sunroof apertures). Sika has developed a range of speciality formulations with ideal characteristics to enable vehicle OEM’s to meet these requirements with optimum quality, consistency and cost.
Sikaflex range provides high-performance easy-to-use one-component formulation with different mechanical properties to meet the various requirements. SikaForce two-component provides the high performance of polyurethane systems combined with long open time and process advantages. SikaPower structural adhesives and sealants are heat-curing products for metal bonding applications based on one- and two-component PUR-epoxy hybrid technology.
Front & Rear Module
The last ten years have seen a dramatic improvement in the aerodynamics and styling of bus and coach vehicles. The front and rear modules of modern vehicles are two of the most visible indicators of such changes. The use of thermoset composites is now common for such applications, and has enabled big changes in vehicle styling and aerodynamic behaviour to be achieved. In addition to these changes, such applications must comply with ever-tougher durability, impact and ease-of-assembly requirements. Sika has formulated a range of materials to exceed customer requirements for this challenging application.
Sikaflex offers 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. SikaFast two-component methylmethacrylate structural adhesives provide high strength and excellent impact resistance with low surface preparation.
For over 20 years, Sika has been providing bus & coach, automotive, truck and rail OEM assembly lines with adhesive and sealant solutions for sealing, bonding and direct glazing. Primerless, manual and automated pretreatment options are available to fit the needs of a variety of OEM application processes in order to create significant cost savings and manufacturing process simplification.
Sika offers a wide range of adhesive technologies to suit all direct glazing applications. Specific Sikaflex solutions are available to suit cold, warm and hot application processes. Proprietary Sikaflex materials are capable of retaining the glass in position following installation, allowing for elimination of secondary clips, fixings and tape. Sikaflex materials can also provide low electrically conductive properties for elimination of galvanic corrosion/antenna signal loss.
