Conventional spray and airless spray
Will yellow with time and chalk on exterior exposure, although the MIO pigment reduces chalking. Neither yellowing nor chalking detracts from the protective properties of the coating. Use a weatherable topcoat if required for appearance.
Heat Resistance
Up to 120°C dry heat.
Water Resistance
Excellent resistance to fresh and salt water but not suitable for immersion.
Abrasion Resistance
Good when fully cured.
Solvent Resistance
Resists splash and spillage of most hydrocarbon solvents, refined petroleum products and most common alcohols.
Acid Resistance
Not suitable for for acid conditions unless topcoated.
Alkaline Resistance
Not suitable for alkaline conditions unless topcoated.
Salt Resistance
Excellent resistance to neutral salts.
