Key Facts
Benzoin is a degassing agent for powder coatings, manufactured by Huangshan Deping Chemical Co., Ltd. Its chemical name is 2-hydroxy-1,2-diphenylethanone. Benzoin removes gases released during curing and thereby prevents defects such as pinholes and bubbles in the coating film. It is a white or light yellowish powder with a melting range of 133-137 °C, a boiling point of 344 °C, and volatiles of at most 1%.
Benzoin can be used in epoxy, hybrid, polyester/TGIC, and matte or textured powder coating systems. The recommended dosage is 0.3-1% by weight of the total formulation, added during the premixing stage; the exact amount should be determined by laboratory testing. Benzoin is packed in PE-lined kraft paper bags of 20 kg net weight and should be stored in a dry, cool place.
Frequently Asked Questions
