Phosmatt

Using a closed-circuit wet blast circuit Vapormatt phosmatt systems can simultaneously phosphate, etch, de-grease, de-rust and de-scale the surface.

The Phosmatt Process uses a heated phosphate solution as the carrier for the abrasive media. This combination causes the chemical action to start immediately between metal substrate and the phosphate solution as a result small, fast growing crystals appear on the nascent surface.

To continue the crystal growth, without re-blasting them away (once all the surface contaminants have been removed), the surface is further rinsed with phosphate solution alone, from a special nozzle. This produces the main build up of the phosphate layer, a very fast build-up which in practice takes only the same time as rinsing the component to remove surface debris.

Phosmatting is also available as a Contract Process Service.
