Railcar door sealant for effective gap-filling and weatherproofing

At Bostik, we specialize in developing high-performing, flame-retardant adhesives and sealants for the rail industry. 

For installation processes where you need to effectively caulk, fill, or seal a gap, we have a broad selection of railcar sealant products.  

Our door sealant technologies are compatible with a variety of substrates typically used for train cars, and can be effectively applied for all seam-sealing and gap-filling applications, whether they lie on the interior or exterior of your vehicle. 

Our rail-specific technologies are specially formulated to not only provide watertight seals, but also endure continually high air pressure and adverse weather conditions, without succumbing to shear stress or other deformities. 

For detailed and professional consultation on how our door sealant products could benefit the longevity and easy maintenance of your rolling stock, contact our technical support team.

Railcar door sealant: technologies

Like the majority of our smart chemical solutions developed specifically for railway applications, our railcar door sealant range is mostly comprised of silyl modified polymers. 

This cutting-edge technology doubles-up as effective tools for sealing, and offers a blend of adhesive and sealant properties to the end user, whether you are looking to protect your exterior doors against the duress of the outdoor elements and high air pressure, or secure your vehicle interior from unwanted odors, vibrations, or noise pollution.

SMPs provide you with better results than traditional manufacturing processes, and do so through cheaper and more efficient means. While damage to mechanical fastenings and bolted on panels is often irreparable, our sealant solutions are easy to maintain and replace – you can simply scrape them off and start over. 

All of our railcar door sealants are free of solvents and isocyanates, providing a more pleasant working experience for your engineers. They are also available in fast-curing and slow-skin formulations, to suit the size, scale, or complexity of the components you are working with. 

We at Bostik are committed to keeping your rolling stock moving for decades to come, which is why our SMP sealants boast great resistance to UV, general ageing and corrosion, extreme air pressure and weather conditions, while providing effective water sealing and caulking to prevent water damage during cleaning. 

Our sealant solutions for rail are specially designed to provide a seal that is both durable and dynamic, in order to endure the continuous movement and stress that rolling stock is constantly put under. Bostik railcar door sealants possess excellent stability of their mechanical properties over a wide temperature range, and will make your vehicle incredibly secure while remaining lightweight.
