60/40 epoxy polyester resin HH2608 outstanding flowability mechanical properties high gloss
HH2608 is a carboxyl polyester resin designed for 60/40 hybrid powder coatings for general purpose.
Hybrid powder coatings are prepared by using epoxy resin and polyester resin as the main raw materials, and at the same time have their own unique properties, so that the produced coating film has excellent levelling, decorative, mechanical properties and strong corrosion resistance. Mainly used for surface coating of automobiles, household appliances, metal furniture, instrumentation, indoor fitness equipment, radiators and other industries.
