Drying time
At 20°C:
Filling primer /130÷300 µm/ ready to sand after drying overnight.
Isolating primer /60÷130 µm/ ready to sand after 3÷4 h.
At 60°C of panel temperature:
Filling primer /130÷300 µm/ ready to sand after baking for 35÷40 minutes and surface cooling (about 2h).
Isolating primer /60÷130 µm/ ready t sand after baking for 25÷30 minutes and surface cooling (about 2h).
Temperatures below 20°C significantly increase the drying time.
IR drying
Filling primer /130÷200 µm/: 10÷15 minutes under short wave.
Isolating primer /60÷130 µm/: 8÷10 minutes under short wave.
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.

Further work
2K acrylic primers can be directly over coated with:
- 2K top coats.
- 1K base coats.
General notes
- Do not exceed recommended doses of the hardener!
- The best repair results can be achieved by painting 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 airways.
- The rooms should be well ventilated.
- Clean the guns and equipment immediately after use.
