Hot Car Bogie

OVERVIEW:    Engineers had previously tried different coatings with varied results. The aggressive environment had required structural steel repairs to be carried out every two years as the regular thermocycling in service exceeds many coatings limitations.

Chemcote had previously completed successful repairs on hot car structures in situ, we were asked to provide the same solution for repairs to the hot car bogies

Abrasive blasting is not always possible on site due to work alongside other trades and tight time frames, mechanical surface preparation is undertaken.


RE 500P is a surface tolerant high temperature resistant epoxy coating. It is an innovative single coat maintenance system with outstanding adhesion to less prepared substrates.

Top coated with RW 500, glassflake filled, high temperature resistant Novolac Epoxy, the system provides excellent corrosion resistance in this environment.
