Product description
1. Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, and the curing agent participating in the cross-linking reaction can form an insoluble and infusible hard coating after heating. No matter how high the temperature is, the coating will not soften like a thermoplastic coating, but can only be synthesized. Since the resin used in the thermosetting powder coating is a prepolymer with a lower degree of polymerization and a lower molecular weight, the coating has better leveling and better decoration, and the low molecular weight prepolymer is cured. It can form macromolecules of network cross-linking, so the coating has better corrosion resistance and mechanical properties. Therefore, the development of thermosetting powder coatings is particularly fast.
1.1 Epoxy powder coating. It is the first type of thermosetting powder coating due to its excellent adhesion to metal, corrosion resistance, hardness, flexibility and impact strength. The formulation of epoxy powder coating is composed of epoxy resin (Epoxy Resin), curing agent (curing agent), pigment (pigment), filler (filler) and other assistants (assistant). The contributions of these several components to the properties of the formed powder coating are mutually limited and influenced, and a suitable formulation is, in practice, the result of the harmony of the various components.
