SURFACE PREPARATION

Steel:

Blast-cleaning to minimum preparation standard Sa 2 ½ acc. to ISO 8501-1.

Average surface profile RZ = 25 - 60 µm

(ISO 8503-4) or acc. to specification.

Ensure substrate is free from dirt, grease, oil and other contaminants detrimental to adhesion.

MIXING

Stir component A using a powered mixer. For manual mixing add component B subsequently at the specified mixing ratio. Stir thoroughly, including sides and bottom of the container, until a homogeneous mixture is achieved. If using plural feeded airless equipment (automatic dosage) a dosage control shall be installed to monitor correct mixing ratio.

 

APPLICATION

Airless spraying:

  • Use a high ratio single or plural feeded airless pump
  • Minimum pump ratio: Min. 45 : 1
  • Spray pressure in gun min: Min. 180 bar
  • Spray nozzle: 0.33 - 0.91 mm (0.015 - 0.036 inch)
  • Spraying angle: ≥ 80°
  • Material temperature: ≥ + 20°C
    (other spray parameters might be suitable depending on equipment)

If possible do not thin Sika® Permacor®-337-96 S!

Under special circumstances up to 5 % Sika® Thinner E+B may be added.


Brushing or rolling:

Only suitable for small areas! Clean and prepare damaged areas by sanding or light blasting of areas to be coated and ensure thorough removal of dust. Then overcoat as soon as possible. Under special circumstances up to 5 % Sika® Thinner E+B may be added.
