Painting of metal surfaces with anti-corrosive epoxy primer


EPOXYCOAT-AC Two-component anti-corrosive epoxy coating



The protection of metal surfaces made of iron or steel, from oxidization or corrosion.



EPOXYCOAT-AC antirust epoxy primer is applied for active anti-corrosive and anti-rust protection of iron and steel surfaces that are to be coated with EPOXYCOAT or DUROFLOOR epoxy systems.

It is extremely hard and resistant to friction. It is particularly resistant to diluted acids, alkalis, petroleum products, to some solvents, water, sea water etc.

It can even be used as a coating on its own if its reddish-brown or grey color is satisfactory. Typical examples of use are the protection of silos, steel bridges, iron roofs, pipes, fences etc.



 Substrate preparation

  1. The substrate must be dry, stable and free of anything which would hinder bonding, such as dust, loose particles, grease, rust or any kind of corrosion.

  2. Depending on the nature of the substrate, it should be prepaired by brushing, rubbing down, sand blasting, etc. and then thoroughly cleaned from dust.


Application of EPOXYCOAT-AC

  1. Components A (resin) and B (hardener) are packed in two separate containers, having the correct predetermined mixing proportion by weight. The whole quantity of component B is added into component A. Mixing of the 2 components should take place for about 5 minutes, using a low revolution mixer (300 rpm). It is important to stir the mixture thoroughly near the sides and bottom of the container, to achieve uniform dispersion of the hardener.
    To prime the surface, 2 coats of EPOXYCOAT-AC are applied with brush, roller or spray gun. The second coat is applied once the first one is dry, but within 24 hours.
    Consumption: 150-200 g/m2 per coat.

  2. Subsequently, in the next 24 hours and after the primer is completely dry, application of the chosen EPOXYCOAT or DUROFLOOR system can take place. If alternatively, EPOXYCOAT-AC is to be used as the final finish, 2 more coats of it should be additionally applied. The second coat follows after the first one is completely dry, but within 24 hours.



  • EPOXYCOAT-AC contains solvents. In cases of applications in closed rooms, measures should be taken for good ventilation.

  • Working time of epoxy systems decreases when ambient temperature rises.

  • Bonding between successive layers may be severely affected by the intervention moisture or dirt.

  • Epoxy layers should be protected from moisture for 4-6 hours after application. Moisture may whiten the surface or/and make it sticky. It may also disturb hardening. Faded or sticky layers in parts of the surface should be removed by grinding or milling and laid again.

  • In case that longer time than predicted interferes between the application of successive layers or in case that old floors are going to be laid again, the surface should be thoroughly cleaned and ground before application of the new layer.

  • Before application, study the safety advice mentioned on the product’s labels.
