• Unlimited recoatable.
• Excellent resistance to atmospheric exposure conditions.
• Good color and gloss retention.
• Cures at temperatures down to -5°C (23°F).
• Resistant to splash of mineral and vegetable oils, paraffins, aliphatic petroleum products and mild chemicals.
• Can be recoated even after long atmospheric exposure.
• Good application properties.

RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

Substrate conditions

• Previous coat (epoxy or polyurethane) must be dry and free from any contamination.
• Previous coat: surface should be sufficiently roughened if necessary Substrate temperature and application conditions.
• Substrate temperature during application at -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
• 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 85%.
• Should condensation on the surface occur during, or soon after application, this could result in color and gloss change.

INSTRUCTIONS FOR USE Mixing ratio by volume: base to hardener 88:12.

• The temperature of the mixed base and hardener should be above 10°C (50°F), otherwise extra thinner may be required to obtain application viscosity • Thinner should be added after mixing the components • Adding too much thinner results in reduced sag resistance.
