Anticorrosive Isolation Primer 3:1

Use

For car repairs as an isolation primer for sanding or wet on wet application.

Mixing ratio by volume

Primer: 3
Hardener: 1

Thinner (black version): 35% for wet on wet, 15% for sanding.

Thinner (grey and white versions): 35% for wet on wet, 20% for sanding.

Mix thoroughly until a homogeneous consistency is obtained.

Spraying viscosity

Black version:
17÷18 seconds at 20°C thinner 35%
about 30 seconds at 20°C thinner 15%.

Grey and white versions:
17÷19 seconds at 20°C thinner 35%.
about 30 seconds at 20°C thinner 20%.

Pot life for the mixture

about 40 minutes at 20ºC

Number of layers

For wet on wet: 1,5 layers; about 30µm of dry layer.
For sanding: 1÷2 layers; about 50µm of dry layer.
RP gun parameters
Nozzle: 1,2÷1,6 mm; Pressure: 2,0-2,2 bar.
HVLP gun parameters
Nozzle: 1,3÷1,5 mm; Inlet pressure: 2,0 bar.

Flash off time

Between layers: about 5÷10 minutes
before applying solvent base system: approx. 20 minutes
before applying water base system: approx. 30 minutes
Flash off time depends on the temperature and the number of layers

Drying time

Drying time at 20°C:
Isolation primer /30÷50 µm/ ready for sanding ater 2÷3 hours.

Drying time at 60°C
Isolation primer /30÷50 µm/ ready for sanding after baking for about 15÷20 minutes and cooling down (approx. 1hour)

Temperatures below 20°C significantly increases the hardening time.

IR drying

Isolation primer /30-50 µm/ : 5÷7 minutes under short waves.
Primer for sending /50÷100 µm/: 8÷10 minutes under short waves.

Do not exceed 60oC.
Use as recommended by the equipment manufacturer.
Wait about 10 minutes before starting IR drying.

Dry sanding

Machine sanding: P360÷P500.
Manual sanding: P320÷P500.

Wet on wet does not require sanding

Wet sanding

Machine sanding: P600÷P1000.
Manual sanding: P800÷P1000.

Wet on wet does not require sanding

General notes

• Do not exceed recommended doses of the hardener!
• The best repair results can be achieved at room temperature. The temperature in the body shop and the temperature of the product should be similar.
• When working with 2K products, it is recommended to use personal protection equipment. Protect the eyes and air ways.
• The rooms should be well ventilated.
• Clean the guns and equipment immediately after use.

Caution: To maintain safety, always follow the instructions given in the MSDS for the products.
