Description

2K light filling epoxy primer with anti-corrosive additives. It works very well as a barrier offering great protection in car repairs. Especially recommended for application wet on wet.

Advantages

Excellent protection of steel surfaces.
Very high adhesion to various substrates.
Easy to mix and apply.
Exceptional fluidity.

Substrates

Anticorrosive epoxy primer can be applied directly on:

Steel and aluminum after matting and degreasing.
Zinc-coated and galvanized steel after matting and degreasing.
Sanded glass fibre-polyester ((GFK/GRP) and glass fibre-epoxy laminates.
Polyester and epoxy body fillers.
Old paint coatings in good condition after matting and degreasing.

Good surface preparation is essential to achieve the best repair results.

Mixing ratio
1 : 1
Spraying viscosity
18 ÷ 20s / 20°C
Pot life
~ 3h / 20°C
1 ÷ 3 layers
HVLP / RP
ø1,2 ÷ 1,6 mm
between layers
5 ÷ 10 min.
before baking
~ 10 min.
Hardening time
5 h / 20°C
35 min. / 60°C

Use
For car repairs, as an isolating primer, for sanding or wet on wet application.

Mixing ratio by volume
Primer: 1
Hardener: 1
Thinner: not required!
Stir thoroughly until obtaining a homogenous mixture.

Spraying viscosity
18÷20 seconds at 20ºC.

Pot life for the mixture
about 3 hours at 20°C

Number of layers
- For wet on wet: 1,5÷2 layers; about 25÷50µm of dry layer.
- For sanding: 2÷3 layers; 100÷140µm of dry layer.
Gun parameters:
RP nozzle: 1.2÷1.6 mm; Pressure of input: 2.0÷2.2 bars.
HVLP nozzle: 1.3÷1.5 mm; Inlet pressure: 2.0 bars.

Evaporation time
Between layers: 5÷10 minutes
Before baking: about 10 minutes
Before topcoating (wet on wet): 45÷60 minutes
Evaporation time depends on the temperature and the number of layers.

Hardening time
- about 5 hours at 20°C (depending on coating thickness).
- about 35 minutes at 60°C (depending on coating thickness).
Temperature below 20°C significantly increases the hardening time.

IR drying
8÷10 minutes under short wave for a coating thickess of 100÷140µm. 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
Sanding paper P400÷P500
Wet on wet application does not require sanding!

Wet sanding
Machine sanding: P600÷P1000.
Manual sanding: P800÷P1000.
Wet on wet application does not require sanding!

Further work
2K epoxy primers can be directly over coated with:
- 2K topcoats.
- 1K basecoats.
- 2K acrylic primers.
- 2K polyester body fillers.
- 2K epoxy body fillers.

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.
- This product cannot be applied on wash primers and 1K primers.
Caution: To maintain safety, always follow the instructions given in the MSDS for the products.
