TMA Free Thermosetting Hybrid Curing Resins For Epoxy Polyester Powder Coatings
TMA Free 70/30 Thermosetting Hybrid Curing Resins for Epoxy Polyester Powder Coatings
Hybrid Polyester Resin TMA Free HH2782G with Good Storage Stability and Balance of Properties for Indoor Use
HH2782G is a carboxyl polyester resin designed for 70/30 hybrid powder coatings with excellent gas oven stability. Can be used with B68 for low gloss with good performance. Also, it’s a completely TMA free hybrid polyester resin.
TMA (Trimellitic anhydride) is respiratory sensitizing and can cause severe and permanent damage to lung function if exposed for prolonged periods of time and without intervention. Therefore, using powder coatings made of TMA free polyester resin as the raw material is safer in indoor use.
