Sandwich Panel Production

Caravan and motorhome manufacturers use a wide variety of substrates in the production. Increased efficiency Good thermal insulation, light-weight construction and high acoustic dampening are required to provide enhanced occupant comfort and better fuel economy.


The use of adhesives to fabricate panels, eliminate the risks of buckling or deformations and improve efficiency, quality and cost. Sika provides solutions to match with different customer process requirements. Systems are available with a wide range of press times, green strengths, open times and other key factors to adapt to the process. Sika offers SikaForce one and two component polyurethane (PUR) technologies, as well as reactive hotmelt (RHM) technology called SikaMelt for such applications.

Direct Glazing

For over 20 years, Sika has been providing caravan and motorhome assembly lines with solutions for direct glazing. Primerless pretreatment options are available to fit the needs of a variety of application processes in order to create cost savings and process simplification.


Specific Sikaflex solutions are available to suit cold, warm and hot application processes. Proprietary Sikaflex materials retain the glass in position following installation, allowing for elimination of secondary fixings and tape. The Sika Booster range provides the ultimate solution for OEM’s seeking excellent mechanical properties with the shortest possible full cure time.

Body Assembly and Exterior Sealing

The mix of materials used to fabricate caravans and RV’s has radically changed. The use of fibreglass composites and sandwich panel structures is now commonplace, as manufacturers seek to reduce vehicle weight, improve fuel economy and enhance thermal insulation and user comfort.


Sika provides high-performance solutions for body assembly. SikaForce two-component PUR adhesives demonstrate high strength, good flexibility and are capable of curing at room or elevated temperatures. Sikaflex PUR sealants and adhesives combine simplicity of application with excellent durability.


Sikaflex Hybrid technology combines the performance of traditional Sikaflex polyurethane systems with additional benefits such as reduced substrate preparation and improved worker safety. SikaFast two-component adhesives combine low surface preparation, high strength and rapid de-jigging. SikaLastomer butyl sealants provide excellent sound damping and sealing properties.

General Bonding and Sealing in Interior

Effective sealing of the vehicle body against water ingress is essential for elimination of expensive warranty costs and quality claims from end customers. Modern vehicle interiors are expected to look stylish, attractive and inviting. Bonded systems allow for the combination of high-performance sealing with improved aesthetics and performance.


Sika has several solutions capable of providing durable elastic sealing and high performance adhesive bonding to many common substrates. Sikaflex polyurethane sealants and adhesives combine simplicity of application with excellent durability. Sikaflex Hybrid technology (based on Sika’s silane terminated polymer technology) combines the performance of traditional Sikaflex polyurethane systems, but demonstrates additional benefits such as reduced substrate preparation and improved worker safety.
