Isocryl® EP-570G is a glycidyl-functional acrylic hardener designed to produce low gloss, exterior-durable polyester powder coatings. Benefits include consistent gloss, smooth matte appearance and dependable performance. Standard and superdurable polyester resins used for TGIC, Primid or Araldite PT-910 powder coatings are well suited for use with Isocryl EP-570G. A key advantage is its improved burnish resistance over conventional matting hardeners and its predecessors Isocryl EP-550G and EP-560G. In addition, Isocryl EP-570G has substantially improved compatibility with polyester/TGIC and epoxy resin based powder coatings.
