Published on 2017-04-06. Author : SpecialChem

COLUMBUS, Ohio -- Hexion is launching two new waterborne epoxy resins at the European Coatings Show, April 4-6 in Nuremberg, Germany. These label-free, low Volatile Organic Compound (VOC) resins enable the manufacture of high-performance, water-based coatings at a competitive cost.

Hexion at ECS 2017: Launches Low-VOC
Waterborne Epoxy Resins

“Our new resins, EPI-REZ™ Resin 6521-WH-56 and EPI-REZ Resin 6531-WH-57, enable formulators to create environmentally-compliant coatings with excellent adhesion to both metals and non-metals,” said Ann Frederix, Senior Vice President, Epoxy Specialties. “Their flexibility and strong corrosion resistance make them well-suited for demanding applications like transportation and heavy duty protective coatings.” These new waterborne epoxy resin dispersions are used alone or as a blend.

Benefits Include:

  • Improved adhesion to a range of substrates, including blank steel
  • Excellent corrosion and water resistance
  • Greater flexibility and impact resistance
  • Enhanced chemical resistance
  • Ease of use and environmental compliance:
  • Longer pot life of up to 6-8 hours 
  • Fast dry, with wet-on-wet recoating options
  • Storage stability at ambient temperature and up to 50°C
  • Greater shear stability, allowing pigment dispersion
  • Very low co-solvent levels, allowing the formulation of very low VOC coatings (< 50 g/l)

The two new resins can be blended to provide a balance of properties, and each has its own features. EPI-REZ Resin 6531-WH-57 provides extra flexibility and impact resistance, making it especially suitable for transportation applications. It also provides a long pot life and contains only 2.5% solvent, resulting in easy-to-use, very low VOC coatings. EPI-REZ Resin 6521-WH-56 provides greater hardness and faster drying with performance similar to Hexion’s NewGen™ Epoxy resin EPI-REZ 6520-WH-53, at an attractive cost. Both new resins are currently produced in Europe.
