Bus and Coach

Body Structure

Bus and coach manufacturers utilise 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.

Floor, Side Panels and Luggage Doors

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.

Roof Bonding

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.

Front and 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.

Direct Glazing

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.

Interior Trim

Vehicle owner operators have driven a significant increase in interior comfort and functionality in recent years, requiring the use of an increasingly diverse mix of interior plastics and fabrics. Performance requirements for interior components have increased, with higher operational temperature requirements, improved emissions/environmental performance needs and reduced component cost/cycle time in production. Sika has developed several solvent-based and water-based solutions to create strong adhesion to many substrates. SikaMelt, SikaTherm and SikaSense technologies are used in the lamination and bonding of a variety of interior applications including instrument panels, interior door trims, carpets, pillar trims, headliners, centre consoles, stowage bins and seat assemblies.
