Note

• The specifications are related to the prepared mixture and are based on standard atmospheric conditions 23/50, DIN 50014.
• Lower temperatures and/or higher humidity will prolong drying and hardening.
• Application below +5 °C is not possible.
• Using winter quality application is possible nearly to frost temperature. Application only on steel supports possible.

Application methods
2K-Deripox Grund BBV 687.

Mixing ratio

• Stirr homogeneous, preferably with mechanical stirrer
• Mix base paint and hardener according to the mixing ratio as specified

Airless spraying

• Flow pressure 180 bar
• Nozzle size 0,013 - 0,015 inch (0,33 - 0,38 mm)
• Spraying angle according to the geometry and size of the object to be laquered
• If required (two component: after mixing) using 5% Deripox-Verdünnung (687.150) is possible

Compressed air spraying

• Spraying pressure 5 - 6 bar
• Nozzle size 1,8 - 2,2 mm
• Adjust to spraying viscosity (appr. 60 s DIN 4 mm) adding appr. 10 % Deripox-Verdünnung (687.150) (two component products: after mixing)

Electrostatic application

• Application is possible provided that the material is diluted

Dipping

• Can not be applied as delivered

Other methods

• Roller and brush application is possible in the quality as delivered

Thinner

• Max. 10% Deripox-Verdünnung (687.150)

Cleaning

• Rinse immediately with Deripox-Verdünnung (687.150)

Preparation of support

• Shot blasting to a purity according to SA 2½
• If necessary clean with high pressure-cleaner and turbo-cleaner-solution
• Sweeping for zinced supports
• Mill scale, welding residues, dust, soluble residues from chemical pretreatments and zinc reaction products which might reduce adhesion have to be carefully and thoroughly removed

General remarks

• During coating and drying the humidity should be min. 10 % / max. 85 %
• During coating and drying the environmental temperature should be min. 5°C / max. 30°C
• Object temperature at least 3° C above dew point.
