Advantages

  • Easy to mix and apply.
  • Short hardening time.
  • Good isolating and filling properties.

Substrates

Acrylic primers can be applied over:

  • Bare steel and aluminum after matting and degreasing.
  • Zinc coated, galvanized steel after matting and degreasing.
  • Sanded polyester laminates (GFK/GRP).
  • Polyester putties.

  • Czas odparowania
  • Evaporation time

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

    Evaporation time depends on the temperature and the number of layers.

  • Czas utwardzania
  • Hardening time

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

    Temperature below 20°C significantly increases the hardening time.
