Description

The highest quality 2K acrylic primer with excellent adhesion to difficult surfaces, in particular aluminum and galvanized steel, as well as polyester putties and old paint coatings. HS primer with very good filling properties for car body repair. Thanks to its very good insulating properties and good corrosion protection, it can be applied directly to bare metal.

Advantages

Excellent adhesion to difficult substrates.
Easy to mix and apply.
Exceptional vertical stability.
Great filling and insulating properties.
Easy sanding.

Substrates

V2012 4:1 acrylic primer can be applied directly on:

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

Mixing ratio by volume
Primer: 4
Hardener: 1
Thinner:
10% (filling version),
20% (priming version).
Stir thoroughly until achieving homogenous mixture.

Spraying viscosity
40 ÷ 50 seconds at 20°C (filling version)
25 ÷ 30 seconds w 20°C (priming version)

Pot life
Approx. 60 minutes at 20°C.

Number of layers
2 ÷ 3 layers; 60 ÷ 300 µm depending on the size of the nozzle gun.
Gun parameters:
RP nozzle: 1,6 ÷ 2,0 mm; Pressure of input: 2,0 ÷ 2,2 bars.
HVLP nozzle: 1,5 ÷ 1,9 mm; Inlet pressure: 2,0 bars.

Flash off time
Between coats: 5 ÷ 10 minutes
Before baking: 5 ÷ 15 minutes
Flash off time depends on temperature and film thickness.

Hardening time
Filling version (130 ÷ 300 µm):
- at 20°C: ready for sanding after overnight drying.
- at 60°C: ready for sanding after baking for 35 ÷ 40 minutes and cooling the coating (about 2 hours).
Priming version (60÷130 µm):
- at 20°C: ready for sanding after 3 ÷ 4 h.
- at 60°C: ready for sanding after baking for 25 ÷ 30 minutes and cooling the coating (about 2 hours).
Temperature below 20°C significantly increases the hardening time.

IR drying
- Filling version (130 ÷ 200 µm): 10 ÷ 15 minutes of short waves.
- Priming version (60 ÷ 130 µm): 8 ÷ 10 minutes of short waves.
Do not exceed 60°C. Use as recommended by the equipment manufacturer. Wait about 10 minutes before starting the heater drying.

Dry sanding
Machine Sanding: P360 ÷ P500
Manual Sanding: P280 ÷ P360

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

Further work
2K acrylic primers can be directly over coated with:
- 2K acrylic topcoats,
- 1K basecoats.

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 air ways.
- Clean the guns and equipment immediately after use.
- The rooms should be well ventilated.
Caution: To maintain safety, always follow the instructions given in the MSDS for the products.
