As well as the development, manufacture and supply of a wide range of speciality chemicals and processes for metal finishing industries PreTreat also offers a range of commercial consumable products too.

Here is just a small selection of the most popular products.

Paint Preparation Wipes

Fasbond® W-720 pre-treatment wipes are synthetic lint-free cloths, impregnated with an iron phosphating solution. Not only do they clean but they also treat galvanised, steel or aluminium surfaces prior to painting. They will remove light corrosion products and replace the surface with a light phosphate coating that helps bond the paint to the surface for improved corrosion protection.

Tacky Oven Coating

A polymeric based coating formulated for use in high-temperature paint ovens. This product is applied to a sheet of steel or aluminium, wrapped in aluminium foil, by a paint roller. Then passed through the oven to trap airborne particulates that may otherwise be deposited on freshly painted surfaces. The coating remains tacky for extended periods of time at temperatures up to 250° C.


Siloxycoat is a clear, ready-to-use polysilazane surface coating, developed to protect and preserve surfaces in a variety of different environments. Application to the carrier material can be either via spray or dip coating, roll-to-roll application or spin coating as well as wipe-on for smaller areas. Once applied and fully dried it creates a permanent barrier by chemically binding to the substrate.
