Mixing ratio by volume

Filler: 5
Hardener: 1
Thinner: 25÷30%

Stir thoroughly until achieving homogenous mixture.

Spraying viscosity
30÷50 seconds at 20°C

Pot life

approx. 60 minutes at 20oC

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; Pressure: 2,0 bar

Evaporation time

Between the layers: approx. 5÷10 minutes
Before baking: approx. 10 minutes

Evaporation time depends on the temperature and layer thickness

Hardening time

Approx. 3-4 hours at 20°C
Approx. 30 min. at 60°C

Temperature below 20°C significantly increases the hardening time.

IR drying

10÷15 minutes of short waves for the thickness of 150÷250 µm. Do not exceed 60°C. Use as recommended by the equipment manufacturer. Wait about 10 minutes before starting the heater drying.

By hand P280÷P320

Wet sanding

By machine P600÷P1000
By hand P800÷P1000

Further work

2K acryl fillers can be directly over coated with:

• 2K acrylic top coats
• 1K base coats

General notes

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