Description

Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties, high purity, good mechanical and thermo-mechanical properties.

Kynar® ADX 281 resin allows primer less powder coating (direct adhesion to metals after standard surface preparation.

Can be used easily in standard application processes:

  • Dip coating in fluidized bed
  • Electrostatic spraying
  • Hot flocking
