APPLICATION DATA

• Application methods: Brush/ Roller, Airless Spray, and Conventional Spray.
• Mixing ratio (by volume): 4 parts Base to 1 part Hardener.
• Thinner: Thinner AT02 (Maximum 5% addition).
• Airless Spray: Nozzle Size: 0.46mm (18 thou) Fan Angle: 65°. Operating Pressure: 155kg/cm² (2200 psi).
• Conventional Spray: Nozzle Size: 1.27mm (50 thou). Atomising Pressure: 2.8 kg/cm² (40 psi). Fluid Pressure: 0.4 kg/cm² (6 psi).
• Brush/Roller: This product is suitable for brush application. Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray-applied coat.

APPLICATION CONDITIONS AND OVERCOATING

This product should preferably be applied at a temperature in excess of 10°C. In conditions of high relative humidity i.e. 80-85%, good ventilation conditions are essential. The substrate temperature should be at least 3°C above the dew point. At application temperature below 10°C, drying and curing time will be significantly impaired. Application at a temperature below 5°C is not recommended. In order to achieve optimum water and chemical resistance, the temperature needs to be maintained above 10°C during curing.
