Application methods
2K DC Lack DTM Hydro

Mixing ratio

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

Airless spraying

• After using the material close the packings immediately
• Dip the pistol and the nozzle into water during the breaks
• It is tending to fast skinning. Do not stir the skin in any case!
• Flow pressure 120 - 160 bar
• Nozzle size 0,011 - 0,013 inch (0,28 - 0,33 mm)
• Suitable for the application on automatical equipments
• Spraying angle according to the geometry and size of the object to be laquered
• Do not exceed wetfilm thickness of 225 µm (blistering)

Compressed air spraying

• Spraying pressure 2 bar
• Nozzle size 1,3 - 1,6 mm
• Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 5 % Water (two component products: after mixing)

Electrostatic application

• Application is possible, provided the equipment is suitable for water based materials

Dipping

• Can not be applied as delivered

Other methods

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

Thinner

• Max. 3% Water

Cleaning

• Rinse immediately with Water
• Residues are dissolvable with Deripox-Verdünnung

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. 30 % / 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.

Example for a system

• Primer coat: 2K-Hydropox Protec ZP*
• Finish coat: 2K DC Lack DTM Hydro
