Testing methods
 
  • Pigment preparations Versanyl are standardised in colour strength and colour shade. These properties are tested on the level of standard depth B = 1/6 by mixing of pigment preparation with the paint BALAKRYL V 2045/0100. Difference in colour strength ± 5 % is guarantined.
  • Content of pigment
     is tested by centrifuge method, small variability against the average value in the table is allowed, the value is not guarantined, because of garancy for colour strength.
  • Content of solids
     2 g of pigment dispersion was dryed in the lab oven at 105 °C till the constant weight. The value is not guaranteed, because it of garancy for colour strength.
  • Specific weight
     determined by pycnometric method. It depends on content of pigment
  • pH
     is determined by measuring of 4 % solution in destilled water. It depends on content of pigment
  • Lightfastness  - Xenotest
     determined by ČSN EN ISO 105-B02; 2000 (80 0147) in deep shade paint and in the level of standard depth B = 1/6, evaluated according to blue scale, by it degree 1 denotes the lowest fastness, degree 8 the highest one.
  • Resistance to alkalis and acids
     1,5 cm wide strips of draw downs at standard depth B = 1/3 were immersed with the dwell time of 5 min. in 2 % solution of caustic soda or 5 % hydrochloric acid, then washed and dryed. The change of the shade was evalued against the not immersed draw down by ISO - Grey scale. Degree 1 denotes the lowest fastness, degree 5 the highest one.
