Cool-Phos from Stowlin CroftshawCOOL-PHOS from Croftshaw Solvents is a low-temperature dynamic cleaning and phosphating process which creates a superbly clean surface at very low environmental cost. The process creates a layer of pure phosphate on the surface of the component, which improves the adhesion of subsequent coatings and provides a good mechanical bond between the paint film and the metal.

The Cool-Phos process is similar to that used in regular vapour degreasing, with a couple of additional stages, and involves immersion in the boiling Cool-Phos solvent followed by spray rinsing with clean distilled solvent. Because Cool-Phos has a boiling point of only 38C, energy consumption is low. The liquid is stable, biodegradeable, and non-flammable. It is ozone-friendly and has no greenhouse gas potential, and does not contribute to low-level atmospheric ozone. Altogether, Cool-Phos is an environmentally-safe process designed to provide high-quality results at low energy cost.

Cool-Phos plant can be successfully fabricated by any reputable plant manufacturer, and full support and back-up is provided by Stowlin Croftshaw. Only one process tank is required, with no secondary drying oven, so plant costs are also low. Operator training is included in the cost of Cool-Phos, and regular site visits by our Technical Service Engineers – of course, at your convenience – and regular laboratory analysis means that confidence in the process will remain high. One-site quality control is as straightforward as checking the uniform blue colour of the emerging parts.

The Cool-Phos process may be applied to many metals, although mild steel, aluminium, and zinc are the most commonly treated. The process gives these metals a surface etch for an extremely deep clean. The one-dip, four stage non-aqueous process usually takes around four to eight minutes, leaving treated parts cool and dry. The main ingredient of Cool-Phos is dichloromethane, along with phosphoric acid and other solvents. The phosphate layer deposited by Cool-Phos protects the metal from moisture, which means that no additional protection is necessary during subsequent storage.
