Traincar door sealant for effective gap-filling and weatherproofing

At Bostik, we specialise in developing high-performance, flame-retardant adhesives and sealants for the train industry. 

For installation processes where you need to effectively caulk, fill or seal a gap, we have a broad selection of traincar 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 train-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. 

Traincar door sealant: technologies

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

This cutting-edge technology doubles up as an effective tool 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 odours, 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 traincar door sealants possess excellent stability in terms of their mechanical properties over a wide temperature range, and will make your vehicle incredibly secure while remaining lightweight.
