Railway Adhesives - Sealing and Bonding Solutions for Rail Industry

Sika's strong presence in the rail industry is the result of our firm commitment. For more than 35 years, Sika's technical and sales experts have proven that our service and solutions enabled suppliers and producers of trains to make their products better, lighter, safer and produce them more efficiently. 

For rail vehicle construction, stringent quality standards are to be applied, such as the EN 15085 series for welding processes, the DIN 6701 series for bonding processes and the EN 45545 series which copes with fire safety issues. Sika has put in place a comprehensive set of data according to DIN 6701-3 requirements, to help it’s customers verify new designs and applications. The DIN 6701-3 material card is continuously monitored to ensure accuracy and quality.

Sika LUM Surface Preps incorporate luminescent dyes for easy detection with UV light. Treated surfaces will temporarily luminesce when exposed to UV light. Thus these solutions provide a visible detection method for verifying primer application  and aligning the process control and safety requirements under DIN 6301 and DIN 2304.

When joining large-sized components for rail vehicles, adhesive application and assembly processes require a longer working time. In contrast, curing speed is essential to move the assembly to the next steps. Selected one-component Sikaflex® assembly adhesives can be used in combination with Sika® Booster to combine extended workability with fast curing. 

SikaFast® acrylic adhesives are ideal for replacing mechanical fixtures such as rivets, screws, or welded joints. SikaFast® acrylic adhesives combine high shear strength and fast strength development with minimal surface preparation for a wide range of bonding surfaces.

Many thermoset composite parts like train masks, toilet modules, or other interior trims consist of different components bonded together. Often this is required to reinforce vehicle parts. Sika's structural polyurethane and epoxy adhesives integrate well with your process requirements. From automation to high cure speed while maintaining enough handling time, SikaForce® and SikaPower® structural adhesives help you increase your production output.

Rail operators demand high-quality door leaves for their fleets as they run under constant mechanical and environmental stresses throughout their service life. SikaPower® structural adhesives fulfill all requirements and withstand harsh climatic conditions and resist all service impacts, thanks to Sika's SmartCore epoxy toughener providing ultimate fatigue performance. SikaPower® structural adhesives provide the door leaves manufacturers a bonding system that improves the performance in the cold- and high-temperature environment. It's simple; with Sika, you can comply with even more challenging specifications put in place for your door leaves by rail OEMs and operators.

Sika offers a wide range of adhesive solutions for the assembly of rail glass and cassette windows. The manual installation requires adequate installation time but decent curing speed. The Sikaflex® glass bonding solutions are suitable for OEM installation as well as for maintenance and repair shops. Easy handling and fast curing are a must. Our Sikaflex® Booster and PowerCure Technology covers all aspects of a smooth and quick application:

Numerous areas inside and outside of a rail vehicle require protection from standing water, water, or dust ingress. Sikaflex® sealing solutions meet the high demands in terms of weathering and rail cleaner resistance. Meanwhile, Sikaflex® sealants meet the required fire standards up to the highest level.

Sikagard® fire-resistant products stop the spread of fire and increase the evacuation time for passengers. They are also used in batteries of e-vehicles to increase passenger protection in the event of a failure in battery cells, arrays, and even the complete module itself.  Further, Sikagard® intumescent coating products are proven throughout other industry applications when activated by heat serving to contain and delay fire spread by increasing in volume and decreasing in density, thus contributing to longer occupant exit time in the event of danger.

Sika enables the accelerating trend of electric operating powertrains; our solutions include intumescent fire protective coatings Sikagard®, thermal conductive SikaForce® adhesives, SikaBiresin® thermal gap fillers, dielectric potting and encapsulation systems, plus Sikaflex® bonding and sealing solutions for battery enclosure assembly.
