Capacryl PU-Matt NAST

High-quality polyurethane-acrylic enamel for interior use.
Special formula for the NAST mist-free spray technology.

Field of Application

Water-dilutable (waterborne) polyurethane-acrylic enamel for professional intermediate and finishing (top) coats indoors. Suitable for use on primed wooden parts as well as for primed metals and unplasticized (rigid) PVC. For mist-free spray application with Caparol Frondend nozzle in combination with the following equipment for spraying:

Wagner XVLP FinishControl 6500 TS
Wagner XVLP FinishControl 5000
Wagner XVLP FinishControl 3500
Titan Focus 700

Note: Matt surfaces are sensitive to stress by scratching and scouring. Preferably use Capacryl PU-Satin/Gloss for surfaces with higher mechanical stress/loads and all permanently touched parts, e.g. in public buildings.

Explanation: NAST /
German term: Nebelarme Spritz-Technologie = Spray technology with low spray mist (dust/fog) formation

  • Low odour.
  • Non-blocking.
  • Diffusion-capable.
  • Resistant to common household detergents.

Material Base / Vehicle

Polyurethane-acrylic dispersion/emulsion

Packaging/Package Size

  • White (Weiß) NAST
     750 ml, 2.5 litres
  • ColorExpress NAST 
     700 ml, 2.4 litres

    A material typical (limited) pigment abrasion may occur on the surface of matt enamels, such as Capacryl PU-Matt NAST, particularly when the product is tinted in dark and intensively coloured shades.

When applying colours with low opacity (hiding power), such as Red, Orange or Yellow, it is advisable to previously apply one priming coat using the matching colour shade of our Priming System. Priming System colours are available via the ColorExpress tinting technique for the following products: Capacryl PU-Matt, Capacryl Haftprimer and Capacryl PU-Vorlack.

Suitable Substrates

Primed wood component parts, primed metals and unplasticized/rigid PVC, indoors.
The substrate must be clean, sound/stable, dry and free from all substances that may prevent good adhesion.

Substrate Preparation

Wooden Parts:
Sand the surface in fibre direction, clean thoroughly and prime with Capacryl Holz-IsoGrund, if necessary. 

Iron, Steel:

Derust according to industry standard SA 2½ (blasting) or ST3 (mechanically) according to DIN EN ISO 12 944-4, followed by an anti-rust priming coat.

Zinc (Galvanised Substrates), Unplasticized/Rigid PVC:
Wash with light ammonia solution or Gescha Multistar using a sanding pad/non-woven web as per German BFS-Merkblätter (Data/Fact Sheets) Nos. 5 and 22. Allow to dry and prime with Capacryl Haftprimer.

Aluminium, Copper:

Clean with nitro-thinner (diluent for cell lacquers) or Multistar using a sanding pad/non-woven web as per German BFS-Merkblatt (Data/Fact Sheet) No. 6 (aluminium). Allow to dry and prime with Capacryl Haftprimer.

Existing Paint Coatings:

Sand the surface and/or treat with alkaline solution. Remove unstable existing coatings and prime as per substrate requirements.

Application:

Capacryl PU-Matt NAST is particularly adjusted for use with the above mentioned spray equipment and special nozzle Caparol NAST-Frontend. Only this combination of material and equipment enables a nearly mist-free spray application.

Spray Technique:
Adjustment for coating surfaces: "Flachstrahl" (flat jet). Spray slowly lengthwise with an overlap of min. 50 % and in a spray distance of 15 cm, applying wet-on-wet.
Do not apply cross-coats!
Allow to dry and apply a second coat in the same manner, if necessary.

1) Definition of suitable application areas: see Technical Information No. 606.
2) Always apply Capacryl Holz-IsoGrund on wood with content of water-soluble, discolouring substances (2x on knots).
3) The intermediate coat should match the finishing coat in shade. For colour shades of low opacity (e.g. red, yellow and orange pigmented) a matching colour is automatically selected via ColorExpress, thus a better opacity is achievable for finishing/top coats. This shade may differ from the selected colour in favour of the hiding power of top coats.
4) Colour shades of low opacity (e.g. yellow/red/orange pigmented) may require an additional coat.
Note: Adhesion must always be tested in advance for powder coatings, coil coatings and other critical substrates by trials (coating a test area on site).

Consumption

Approx. 120 - 160 ml/m2 per coat.
Consumption is a guide value and may vary, depending on substrate requirements. Determine the exact amount of material required by coating a test area on site.
