Bilt Hamber Electrox is a well known zinc-rich anti-corrosion coating for steel.

Electrox protects steel from corrosion with both barrier and electrical functionality. Coating steel with Electrox produces a surface film containing over 90% metallic zinc.


  • Provides class-leading corrosion protection.
  • Protects by cathodic action.
  • Contains more than 90% zinc in dry film.
  • Easy to use single-pack material.
  • Easily topcoated with wide range of finishes.
  • Self-healing if damaged.
  • Can be left uncoated – maximum protection achieved when top coated.
  • Can be brushed or sprayed.

Once cured, the tightly packed zinc particles establish an electronically conductive pathway, enabling cathodic protection of the underlying steel; exactly the same principle utilised in hot zinc galvanising.

For years, galvanised steel has proven to provide outstanding longevity even in the most hostile and aggressive environments. It’s unfortunate that the process involves hot dipping steel into a bath of liquid zinc.

For many items and projects this is, of course, simply not possible. For those wanting to provide the very best protection to steel, Bilt-Hamber’s Electrox allows the advantages of a zinc coating to be obtained as simply as if a normal metal primer were being used. It can be applied by brush or by spray, and as it is a single pack product there is no need for mixing activators. The cured zinc film can be left uncoated or top coated with a wide range of finishing paints to further increase protection

Recommended Uses

Electrox is recommended for use on offshore structures, harbour installations, jetty and pier pilings and extreme duty vehicle chassis work.

Electrox is of particular benefit in vehicle restoration where underbody protection is of vital importance. The highest levels of corrosion protection can easily be imparted to chassis rails, floor pans, sill sections, suspension components etc., in fact any area or part can be protected with this outstanding primer.

A Comparison

Most paint coatings rely on barrier protection of steel surfaces to prevent corrosion, and while most have corrosion inhibitor pigments to improve longevity, the long-term protection is often disappointing. Protection of these barrier type coatings is quickly diminished at impact and damage sites too.

A cured film of Electrox is a true zinc-rich coating containing in excess of 90% pure zinc. Proven through thousands of hours of salt-spray testing, zinc-rich coatings are accepted as irreplaceable in the most hostile corrosive conditions. Furthermore, the protection imparted by cathodic action means that steel surfaces are kept free of corrosion even in the event of film disruption.

How to use Bilt Hamber Electrox

Ideally apply to steel surfaces prepared to Swedish Standard SA 2.5 (Second Quality BS. 4232) Do not exceed 75 micron surface profile.

Electrox can be used to protect rusted, wire-brushed substrate – remove all loose flaky corrosion deposits. All surfaces must be free of grease, oil and millscale.

Ensure all edges are protected. Apply one full coat, do not over brush.

For severe, marine duty the application of a second coat after three hours is recommended. Each coat should be applied to WFT (wet film thickness) of 100 microns to achieve around 42 microns DFT (dry film thickness) per coat.

Surface dry in 20-30 minutes. Hard dry three hours.

Over coating can be carried out once film is hard dried, but high solvency top coats should be applied after 24 hrs. Electrox can be overcoated with a wide-range of topcoating systems – check compatibility on small scale before use. Where surface is likely to be subject to mechanical impact from debris overcoating with stone chip protection is desirable.

Coverage 8-10 sq metres per litre
