PPG Sigma AquaCover 40 is a one-component, waterborne acrylic dispersion finish/topcoat with good weather resistance and excellent adhesion to primed steel.

Features

• Particularly suitable when solvents are not permitted because of health and safety reasons
• Good weather resistance
• Good color retention
• Fast-drying
• Fast-handling
• Not suitable for immersion in water

Recommended Substrate Conditions and Temperatures 

Substrate conditions

• Steel coated with suitable primer (e.g. SIGMA AQUACOVER 20)
• Suitable primer must be dry and free from any contamination

Substrate temperature and application conditions

• Substrate temperature during application and curing should be above 5°C (41°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%

Instructions For Use

• Stir well before use
• The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
• Too much tap water results in reduced sag resistance
• Must be protected from freezing at all times during storage and/or transport
