◎Introduction
HH2784 is a carboxyl polyester resin designed for 70/30 hybrid powder coatings.
Thermosetting powder coatings are mainly composed of resins, curing agents, pigments and fillers, additives, etc. Pure polyester powder coatings and mixed powder coatings are the most important varieties in the domestic thermosetting powder coatings market, which are mainly used in household appliances, hardware components, metal furniture and other fields.
hybrid type powder coating is also called polyester epoxy hybrid type powder coating. It can be divided into three types: 50/50, 60/40 and 70/30 according to the curing ratio of polyester and epoxy resin.
70/30 hybrid resin is a new product developed on the basis of 60/40 to further reduce the amount of curing agent epoxy resin.
