‘Bringing New Ideas To The Surface’

Bespoke Consumable Products

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 complimentary consumable products too.

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

Our range of Pre-Treatment Paint Preparation Wipes has been created for the treatment of metal substrate prior to powder coating or wet-paint finishing.

Not only do they clean but they also apply a protective coating that helps bond the paint to the surface for improved corrosion protection.

Their main purpose and usage is in manufacturing environments where parts to be treated are too large, or quantities too small, to justify dip applications, or no booth exists to spray an etch primer.

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 pass 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.

Available in Gloss, Satin or Matt finish, our Touch-Up Pens provide a simple and easy solution to repair and refinish scuffs and scratches on any colour of Powder Coated Paint surface.

Simply follow the instructions to mix a small amount of the original powder coating paint to the pens’ transparent base compound to ensure a good quality finish and colour match.

Touch dry in around 20-30 mins and fully dry within 8-10 hours, our Touch-Up Pens are ideal for fast results!

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.
