Protect axles from corrosion
Axle corrosion on rolling stock is a costly business. It is the main reason why up to 3,000 axles have to be replaced every year at a cost of £1,500 per unit. To address this problem Henkel has introduced its Loctite Axle Corrosion Protection System. The company has many decades of experience in protecting metals against corrosion and also in the specific requirements of the rail sector.
>This new introduction comprises a suite of proven Loctite products, the first of which pre-treats the substrate to inhibit corrosion and promote adhesion. A flexible sealant is then applied to prevent corrosion at the axle transition and wheel overhang. This is topped by a fast-curing 2-part paint system that provides impact resistance and a very smooth surface finish.
>The paint system products are from the Loctite Nordbak range which offers distinct advantages over traditional repair methods such as hard metal welding or flame spraying, both of which are difficult and costly to apply to large surfaces. In contrast the Loctite Nordbak 7255 and 7226 are easily applied on all surface sizes, do not introduce any heat stress and offer the extra benefit of further corrosion protection.
