Ekolak PE/P gloss

high gloss (PE/P-01-1-xxxxx),
gloss (PE/P-01-2-xxxxx),
rough structured (PE/P-21-4-xxxx) and
fine structured (PE/P-11-5xxxx)

General information:

  • Base: binding on the basis of saturated polyester resins, specially selected according to their resistance to the weather conditions and UV radiation
  • Colour shade: according to RAL-card or according to the sample
  • Packaging: 25 kg cartons or big-bags of 500 kg

Powder properties:

  • Density (DIN 55 990/3): 1,2 to 1,7 g/cm3, depending upon the shade.
  • Yield: 9,8 to 13,8 m2/kg at coat thickness of 60 µm, depending on the shade.
  • Granulation (Malvern particle sizer): above 40 µm....40-55 %
  • Method of application: traditional CORONA procedure, negative voltage 30-100 kV, possible supply of powder adequate for TRIBO system of application (mark T i.e. PE/P -01-1-XXXXXT).
  • Stoving conditions: 180 °C/10 min, object temperature, more reactive coating available upon request with stoving temperature 160 °C/10 min.
  • Storage time: 12 months at the temperature below 25 °C for standard coatings, 6 months at the temperature below 25 °C for low stoving coatings.

Mechanical and technological features of the Polyester/HAA Ekolak:

To determine its mechanical properties the Ekolak was applied to the 0,6 mm thick cold-rolled metal sheet degreased with acetone, and stoved in the oven at the temperature of 180 °C for 10 min, i.e. it was submitted to the conditions, required for the particular type of the Ekolak.

  • Coat thickness: 55-80 µm (60-90 µm for structured coatings)
  • Gloss (DIN 67 530, ISO 2813): 60-90 % at the angle of 60°
  • Hardness on Bucholz scale (DIN 53 153): minimum 91
  • T-bend: minimum T2-OK/OK
  • Impact test (DIN 55 669): direct: minimum 100 cm x kg
                                            indirect: minimum 100 cm x kg
  • Adhesion (DIN 53 151): Gt 0

Resistance to the weather conditions - accelerated aging, QUV test; Test conditions:

cycle - 8h UV at 60 °C + 4h 100% humidity at 40 °C, used bulbs: UV A 340 (340 nm)

Changes in the gloss intensity in dependance to the accelerated aging is shown in the following chart:
