    RWIP120 Epoxy Coating and Maintenance System for the Rail Industry

    epoxy coating for rail

    Summary. Indestructible Paints Ltd, a UK specialist, has launched the RWIP120 epoxy coating for rail and high-performance epoxy coating applications. Utilising advanced polymer technology, this product offers excellent corrosion protection, extending the lifespan of rail assets. Suitable for various substrates, its benefits include resistance to heat and chemicals.


    Indestructible Paints Ltd established themselves as a UK manufacturer long ago. We are specialists in high-performance protective coating systems. Therefore, we supply industries such as rail, aerospace and land defence industries. Utilising the latest polymer technology. Indestructible Paint Ltd have been adopting this technology for use, within the passenger and freight rail sectors.

    For instance, underground vehicles, offering excellent corrosion protection in aggressive operating conditions. Consequently, extending the operating life for its customers assets.

    Indestructible RWIP120: High-Performance Protective Coating in Focus

    The first fully compliant product from Indestructible Paint Ltd for use on under-frame components is RWIP120. This high-performance epoxy coating is a high solid solvent-based product.

    Furthermore, you can apply it directly to the substrate as a single coat or use it in a 2-coat application with a primer and finish. You can also overcoat it with itself or other finishes from Indestructible Paint, including epoxy and polyurethanes.

    Indestructible Paint developed RWIP120 as part of their family of coatings. They manufacture it from a high-grade 2-part epoxy system, which they initially procured for aerospace applications. However, Indestructible have subsequently taken this resin binder system to manufacture a range of low VOC coatings. Furthermore, these are intended for rail, industrial, transport and architectural applications. These coatings are ideally suited for use on under-frame components. For instance, bogies, wheel-sets, motors, fluid or air receivers, control enclosures, support structures, etc.

    The composition of the epoxy as well as its chemical bonding properties, allows the use, on a range of substrates. This includes, ferrous and non-ferrous metallics, GRP mouldings and a wide range of composites. Additionally, the cured coating is a tough chemically resilient finish. It has been tested against a variety of corporate and national standards. For example, CR/PE0102 and EN45545-2 for Fire Smoke and Toxicity.
