Painting of metal surfaces with anti‑corrosive epoxy primer
RELATED MATERIALS
– EPOXYCOAT‑AC – Two‑component anti‑corrosive epoxy coating
I. NATURE OF THE PROBLEM – REQUIREMENTS
The protection of metal surfaces made of iron or steel from oxidation or corrosion is essential. The primer used must provide active anti‑corrosive and anti‑rust protection and act as a bonding coat for subsequent epoxy coatings.
II. SOLUTION
EPOXYCOAT‑AC antirust epoxy primer is used for active anti‑corrosive and anti‑rust protection of iron and steel surfaces that will be coated with EPOXYCOAT or DUROFLOOR epoxy systems. It is extremely hard and resistant to friction. It shows remarkable resistance to diluted acids, alkalis, petroleum products, some solvents, water and sea water. It can even be used as a final coating if its reddish‑brown or grey colour is acceptable. Typical applications include the protection of silos, steel bridges, iron roofs, pipes and fences.
III. APPLICATION
Substrate preparation
1. The substrate must be dry, stable and free of loose particles, grease, rust or any kind of old paint.
2. It is recommended to sandblast or mechanically clean metal surfaces to ensure proper bonding.
Application of EPOXYCOAT‑AC
1. Mix components A and B in the specified ratio and stir well with a low‑speed mixer until a uniform mixture is obtained.
2. If required, thin the mixture with up to 5‑10% of solvent SM‑14 to obtain the desired workability.
3. Apply the primer with brush, roller or airless spray in one or two coats to a total consumption of about 150–200 g/m² per coat.
4. Allow the first coat to dry (approx. 24 hours at 20 °C) before applying the second coat or subsequent epoxy coatings.
IV. REMARKS
– Ensure good ventilation in confined working areas to remove solvent vapours.
– Working time of the mixture is reduced at high temperatures.
– Surfaces must remain dry and free of moisture during application and curing.
– If the interval between coats exceeds 24 hours, lightly sand the surface to ensure good bonding.
– EPOXYCOAT‑AC components are flammable and harmful. Wear protective gloves and goggles and avoid skin contact and inhalation of vapours.
