To start cross-linking, the material temperature must exceed the critical temperature of the end-capping agent.Pure polyester powder coating Pure polyester powder coating is one of two commercially available polyester powder coatings (the other is polyester-triglycidyl isocyanurate.
Their outdoor applications include courtyard furniture, car tires and accessories, lawn mowers, and many other products that require high-quality finishes. In addition, the polyurethane-polyester powder coating is tough and has a good appearance. Polyurethane cured polyester powder coating is polyurethane-polyester powder coating The main model of Hybrid Epoxy Polyester Powder Coatings the powder coating has been used for several years.
In the pure polyester powder coating system, the use of e-caprolactam as a blocking agent to control crosslinking has been a very common method. The deblocking temperature of e-caprolactam is about 182°C.. , And has excellent weather resistance.
The outdoor performance of this powder coating is chemically comparable to the polyurethane coatings used on airplanes, buses, trucks, etc. As far as the appearance of the coating is concerned, the polyurethane-polyester powder coating can be said to be a real competitor for those high-quality liquid coatings. It is green and environmentally friendly, does not contain heavy metals, and conforms to international general standards.
Can transfer wood grain, patterns and other patterns to meet decorative requirements. Pure polyester powder coating carton packaging is not a risk product such as flammable and explosive, and logistics fees are charged according to ordinary bulk and container cargo. Outdoor powder coatings are used outdoors without losing gloss or discoloration.
