PERKINS BLUE PAINT 87

Function and technical context

Blue 87 paint for Perkins engines is a specific finish designed for the protection and visual recognition of the blocks and external components of inboard engines. It acts as a barrier against corrosion, marine humidity and chemical agents present in the engine room environment, preserving the integrity of exposed metal surfaces. Its characteristic blue tone corresponds to the color code used by Perkins in its range of marine diesel engines, which facilitates quick identification of the propeller and guarantees a uniform finish after repairs, overhauls or replacement of components. Applying the right enamel is not just an aesthetic issue: a deteriorated layer of paint leaves the metal unprotected against accelerated oxidation caused by the saline environment and constant condensation in engine chambers.

When to replace or reapply this paint?

The most common symptoms that indicate the need to reapply the enamel are the appearance of surface rust, chipping, bubbles under the paint layer or visible loss of the manufacturer's blue color in exposed areas of the block or cylinder head. It is recommended to inspect the condition of the finish during each seasonal maintenance and repaint the affected areas before the oxidation advances towards the base metal, since once the corrosive process takes hold it can compromise the tightness of nearby covers and joints. Reapplying preventively during annual maintenance is the most economical practice to avoid higher cost interventions associated with progressive corrosion of the block.
