Features & Benefits

• General-purpose epoxy primer in protective coating systems for steel structures in atmospheric exposure.
• Particularly suitable when solvents are not permitted because of health and safety reasons.
• Excellent rust preventing properties in industrial or coastal atmospheres
• Good adhesion to steel and galvanized steel.
• Free from lead- and chromate-containing pigments.
• Can be overcoated with most dispersion and alkyd paints, and two-component durable finishes.
• Easy application by brush/roller and (airless) spray.
• Suitable for application on concrete.

Drying Times

Surface Preparation

Substrate Conditions

• Steel; blast cleaned to ISO-Sa2 or power tool cleaned to ISO-St2 for good corrosion protection.
• Galvanized surfaces are variable and the preferred method of treatment is to lightly sweep blast followed by degreasing and cleaning.
• Concrete; surface must be cured, clean, dry and free of desintegrated or chalky materials.

Substrate Temperature & Application Conditions

• Substrate temperature during application and curing should be above 10°C (50°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point.
• Relative humidity during application and curing should not exceed 75%.

Application Methods

Mixing ratio by volume: base to hardener 70:30

• The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity.
• Water should be added after mixing the components.
• Adequate ventilation must be maintained during application and curing.
• Must be protected from freezing at all times during storage and/or transport.

Airless Spray:

• Recommended thinner: Tap water.
• Volume of thinner: 0 - 5%, depending on required thickness and application conditions.
• Nozzle orifice: Approx. 0.48 mm (0.019 in).
• Nozzle pressure: 15.0 MPa (approx. 150 bar; 2176 p.s.i.).

Brush/Roller:

• Recommended thinner: Tap water

Volume Of Thinner

• 0 – 5%

Cleaning Solvent

• Tap water and THINNER 40-25, THINNER 70-05 or THINNER 70-04

Cleaning Procedures

• Pulsator filter and tip filter must be taken out of the equipment and cleaned properly.
• The following tables illustrate the cleaning procedure of the spray equipment when changing from spraying with solventborne paint to waterborne paints (table 1) and from waterborne paints to solvent-borne paints (table 2).

Health & Safety

• Although this is a waterborne paint, care should be taken to avoid inhalation of spray mist, as well as contact between the wet paint and exposed skin or eyes.
• For further information please see the safety data sheets in the attachments section above.
