Storage
Shopprimer Hydro NeoWeld

Storage

• In dry, cool rooms, frost-proof
• Ensure good ventilation

Shelf life

• 6 month from date of delivery when in unopened original containers in cool and dry conditions

Application methods
Shopprimer Hydro NeoWeld

Mixing ratio

• Stirr homogeneous, preferably with mechanical stirrer

Airless spraying

• Risk of spray dust due to very fast drying
• 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 70 - 100 bar
• Nozzle size 0,013 - 0,019 inch (0,33 - 0,48 mm)
• Suitable for the application on automatical equipments

Compressed air spraying

• Can be applied as delivered
• Spraying pressure 4 bar
• Nozzle size 1,3 - 1,5 mm

Electrostatic application

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

Dipping

• Can not be applied as delivered
• Adjust to working viscosity (appr. 23 s DIN 4 mm) by adding appr. 2 % Water

Other methods

• Roller and brush application for repair work is possible

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
• Mill scale, welding residues, dust and dirt on the surface 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 %
• Object temperature at least 3° C above dew point.

Example for a system

• Primer coat:
• Finish coat: Miscellaneous
