Basic data at 20 °C (68 °F)

Parameters after mixing

Max 144.0 g/L (approx. 1.2 lb/gal) (theoretical value)

Maximum time: 3 months

Curing agent: at least 12 months; store in a dry and cool environment

Notes

• See the supplementary data sheet — theoretical spreading rate versus dry film thickness table
• See supplementary parameters — recoat interval table

Recommended substrate condition and temperature

Substrate condition

• Bare steel: blast cleaning to Sa2½ of ISO 8501-1, with a surface profile of 50–100 µm (2.0–4.0 mil)
• Steel already coated with a compatible maintenance primer: ensure the coated surface is clean and dry and all contaminants are removed.
• If a temporary maintenance primer is required, select High-solids Phenolic Epoxy Primer 260 or Universal Epoxy Primer 280

Instructions for use

Mixing ratio by volume: base : curing agent = 75:25 (3:1)

• Before application, adjust the temperature of the base, curing agent or mixed paint to at least 20 °C (68 °F)
• At low temperatures, spraying may be difficult because of high paint viscosity.
• Do not add thinner

Induction Time

Not required

Airless spray (single-feed pump)

Spray fan angle

30° – 40°

Nozzle tip size

Approx. 0.66 mm (0.026 in)

Notes

• With single-component airless spray equipment, select a heavy-duty 60:1 pump and suitable high-pressure hose
• For application at low temperature, a heated or insulated hose may be required to keep the paint warm
• The hose should be as short as possible
