Application process


For car body repairs.

Mixing ratio

By weight
Primer: 10
Hardener: 1
Thinner: 20÷30%

By volume
Primer: 10
Hardener: 1,5
Thinner: 20÷30%

Mix thoroughly until a homogeneous consistency is obtained.

Sprayin viscosity

30÷50 seconds at 20°C

pot life for the mixture

about 1,5 hours at 20°C

Number of layers

2÷3 layers.
RP gun parameters
Nozzle: 1,6÷2,0 mm; Pressure: 2,0÷2,2 bar.
HVLP gun parameters
Nozzle: 1,5÷1,9 mm; Inlet pressure: 2,0 bar.

Flash off time

Between layers: approx. 10 minutes
Before baking: approx. 15 minutes

Flash off time depends on the temperature and the number of layers.

Drying time

about 8 hours at 20°C (depending on the coat thickness)
about 45 minutes at 60°C (depending on the coat thickness)

Temperatures below 20°C significantly increases the hardening time.

IR drying

10÷15 minutes under short wave for coating thickness of 150÷200 µm.
Do not exceed maximum temperature of 60°C.
Use according to the recommendations of the equipment manufacturer.
Wait about 10 minutes before starting IR drying.

Dry sanding

Machine sanding: P360÷P500.
Manual sanding: P280÷P320.

Wet sanding

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

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.
