V2012 HS 4:1

Use

For car refinish as a filling primer or isolating coating.

Mixing ratio by volume

Primer: 4 parts
Hardener: 1 part
Reducer: 10÷15%

Mix well until smooth mixture is achieved.

Spraying viscosity

30÷40 seconds at 20°C(68°F)/DIN4.

Pot life

Approx. 60 minutes at 20°C(68°F)/DIN4.

Evaporation time

Between layers: 10÷15 minutes
Before baking: 15 minutes

Evaporation time depends on the temperature and the thickness of layers.

Dry sanding

Machine sanding: P360÷P500.
Hand sanding: P280÷P360.

Wet sanding

Hand sanding: P600÷P1000.

Number of layers

2÷3 layers; 130÷300µm depending on the size of the gun nozzle.

RP spray gun:
Nozzle: 1,6÷2,0 mm;
Pressure : 2,0-2,5 bar.

HVLP spray gun:
Nozzle: 1,5÷1,9 mm;
Pressure: 0,7 bar

Hardening time

Curing time at 20°C:
Thick coating /130÷300 µm/ is ready to sand after drying overnight.
Thin film /60÷130 µm/ is ready to sand after 3÷4 h.

Curing time at 60°C object temperature:
Thick coating /130÷300 µm/ is ready for sand after baking for 35÷40 minutes and cooling down (about 2 h).
Thin film /60÷130 µm/ is ready to sand after baking for 25÷30 minutes and cooling down (about 2 h).

Temperature below 20°C(68°F) significantly decreases the hardening time.

IR Drying

Thick coating (up to 180µm): 15÷20 minutes of short waves.
Thin coating (up to 130µm): 10÷15 minutes of short waves.

Drying time may change depending on the type of heater.
