Cooling Tower

These scans show a typical cooling tower which had previously been coated with epoxy paint. The Epoxy had approached the end of its useful life due to sub-film corrosion, low elongation properties of the Epoxy and subsequent de-bonding.

The tower was also leaking from some of the joint seams.

All internal surfaces of the tower were prepared by means of dry abrasive blasting in order to remove the existing epoxy and raise a suitable surface profile on the substrate to promote adhesion of the high performance coating system.

All mastic in the seams was cut back flush and new mastic applied, prior to all seams and sharp edges, etc, being 'stripe coating' with 3M Scotchkote 165PW Solvent Free Polyurethane.

The product was then applied 'wet on wet', by means of Plural Component, Hot Applied, Specialist Spray Equipment in order to achieve a total, nominal, thickness of 1000 Microns (1mm).

A ten year 'single source responsibility' Guarantee was then submitted to the client along with a COVAC Completion Report including photographs taken of strategic stages of the contract.
