Description
2K epoxy primer designed for car body repairs. It can be applied directly to metal, protecting steel surfaces against corrosion.
Advantages
- Very high adhesion to various surfaces.
- Easy to mix and apply.
- Short hardening time.
Substrates
Epoxy Primer 10:1 can be applied over:
- Steel and aluminum after flatting and degreasing.
- Zinc coated steel galvanized steel after flatting and degreasing.
- Sanded polyester-glass laminates (GFK/GRP) as well as epoxy-glass laminates
- Polyester and epoxy putties
- Old finishes in good condition after flatting and degreasing.
- Good surface preparation is essential to achieve the best repair results.

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.
Further work
2K epoxy primers can be directly over coated with:
- 2K top coats
- 1K base coats.
- 2K acrylic primers
- 2K polyester putties.
- 2K epoxy putties
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.
