Product Description:


Isocryl® EP-570GA 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-570GA. 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- 570GA has substantially improved compatibility with polyester/TGIC and epoxy resin based powder coatings.

Designed to achieve <10 gloss pigmented coatings with a variety of standard and super-durable resins in a single extrusion system. Best results for chemical and mechanical properties are achieved by formulating a polyester resin with acid value 35 and Isocryl EP-570GA at a 75:25 ratio with a second crosslinker such as Primid® XL-552 at 1% on total formulation. Resins with acid value below 30 are not recommended for use with Isocryl EP-570GA. Primid QM-1260 or TGIC are also suitable as a second crosslinker. It is not recommended to use the secondary crosslinker at a level higher than 1.3% due to uncontrolled gloss variation during processing and application. Formulations with Isocryl EP-570GA are very stable to multiple extrusions indicating good process stability and have minimum gloss change with different cure temperatures, film thickness variations or part mass. Part of Isocryl EP-570GA can be replaced with Isocryl EP-575GA to optimize mechanical and chemical properties.

It is recommended that formulated powders be tested for physical and chemical advancement when stored at elevated temperatures. Recommended storage temperature is below 40°C.

Recommendation for Use

  • powder coatings
  • architectural
  • burnish resistance
