Henkel’s Kephos 253 is a non-aqueous phosphating treatment for iron and steel surfaces, which simultaneously protects and seals the surface to protect against corrosion and enhance paint adhesion.

Typical applications for Kephos 253 are the phosphating of bodywork panels, cycle frames, car accessories, machinery casings including meter boxes and domestic white goods, and sheet steel.

It can be sprayed in a standard painting booth or dipped in a conventional tank.

Applied at ambient temperature, Kephos 253 works well with a conventional spray gun but also lends itself to electrostatic spray, roller or brush coat, cold dip, or wiping.

Its compatibility with spray applications make it suitable for large items that are difficult to immerse.

It is commonly applied to iron and steel, as well as brass, electroplated zinc and galvanised items.

As it is non-aqueous, it leaves no water residue, which can lead to paint blistering.

The phosphated coating is quite flexible, allowing sheet materials to be worked up into, for example, box sections after being treated.

Air drying is usually sufficient (3-5min for spray or brush, up to 30min for dip application) although force drying for five minutes at 95C is also permitted.

Treated items can be painted immediately or stored temporarily.
