Testing of paint and
varnish materials

EN/ISO methods:

  • Resistance to liquids
  • Percentage mass of non-volatile matter
  • Percentage volume of non-volatile matter
  • Flow time by use of flow cups
  • Surface drying test
  • Film elasticity under bending
  • Adhesion of coating
  • Gloss
  • Grain sise (granularity)
  • Dry film thickness determined on base of content of non-volatile matter
  • Film thickness (dry, wet)
  • Water-vapour transmission rate (permeability)
  • Liquid water permeability
