RWIP120 Epoxy Coating and Maintenance System for the Rail Industry

Indestructible Paints Ltd have long been established as a UK manufacturer of high-performance protective coating systems for supply into the 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, including underground vehicles, offering excellent corrosion protection in aggressive operating conditions, extending the operating life for its customers assets.

The first fully compliant product from Indestructible Paint Ltd for use on underframe components is a high solid solvent-based epoxy product, RWIP120, applied as a single coat application direct to substrate or 2 coat application, primer, and finish, which can be overcoated with itself and other Indestructible Paint finishes, epoxy, and polyurethanes.  RWIP120 is part of a family of coatings developed by Indestructible Paint, manufactured from a high grade 2-part epoxy system initially procured for use in aerospace applications. Indestructible have subsequently taken this resin binder system to manufacture a range of low VOC coatings intended for Rail, Industrial, Transport and Architectural applications.   These coatings are ideally suited for use on underframe components including bogies, wheelsets, motors, fluid or air receivers, control enclosures, support structures, etc. The composition of the epoxy and its chemical bonding properties allows use on a range of substrates including ferrous and non-ferrous metallics, GRP mouldings and a wide range of composites. The cured coating is a tough chemically resilient finish that has been tested against a variety of corporate and national standards including CR/PE0102 and EN45545-2 for Fire Smoke and Toxicity.

Rail Applications of RWIP120

The Benefits of RWIP120
