What is Thermosetting powder coating:

1. Thermosetting powder coating refers to a thermosetting resin as a film-forming substance, and a curing agent which is subjected to a crosslinking reaction is heated to form an insoluble and infusible hard coating. The temperature is higher and the coating does not soften like a thermoplastic coating, but only decomposes. Since the resin used in the thermosetting powder coating is a prepolymer having a low degree of polymerization, the molecular weight is low, the leveling property of the coating is good, the decoration is good, and the low molecular weight prepolymer is cured. It can form a network cross-linked macromolecule, and thus the coating has better corrosion resistance and mechanical properties. Therefore, the development of thermosetting powder coatings is particularly rapid.

1.1 Epoxy powder coating. It is the first application in thermosetting powder coatings due to its excellent adhesion to metals, corrosion resistance, hardness, flexibility and impact strength. Epoxy powder coatings are formulated from Epoxy Resin, curing agents, pigments, fillers, and other assistant . The contribution of these components to the properties of the resulting powder coating is mutually constrained and influential, and a suitable formulation is actually the result of the coordination of the various components.

1.2 Polyester powder coating. Polyester powder coatings have unique properties compared to other types of powder coatings. It is better in weather resistance and UV resistance than epoxy resin. In addition, since the polyester resin has a polar group, the powdering rate is higher than that of the epoxy resin, the yellowing process is not easy to yellow, the gloss is high, the leveling property is good, the paint film is full, and the color is light, so that Very decorative. Generally used in refrigerators, washing machines, vacuum cleaners, instrument housings, bicycles, furniture and other fields.

1.3 Acrylate powder coating. Acrylic resin powder coatings are both thermoplastic and thermoset. The most advantages of thermosetting acrylic resin powder coatings are excellent weather resistance, color retention, stain resistance, strong metal adhesion, and excellent appearance of the coating film, which are suitable for decorative powder coatings.

Advantages of Thermosetting Powder Coat :

Our Thermosetting Gloss Powder Coat have many advantages,such as Good adhesion,anti-corrosion,UV resistant, strong coating film,Accurate colors, good leveling and so on,we believe that we PURDA powder coating is your best choice.

Application of Thermosetting Powder Coat :

1. First the part must be prepared. It must be thoroughly cleaned so that the powder coating will stick smoothly to it.There are both mechanical and chemical ways to prepare the part. Which method is used depends entirely on the type of part it is, its size, and what type of material it is made of.
2. Second, the powder is actually applied to the part. Powder is applied to most metal objects by spraying it on with an electrostatic gun. The gun gives the powder a negative electric charge, and the object is grounded. In other cases, the powder is sprayed using compressed air. There are many different nozzles that can be used, depending on the type, shape, and size of the object that is being coated in powder.
3. And finally, it is cured by being baked in an oven. The curing process in powder coating is known as crosslinking, and depending on the type of coating that is being used, it requires a specific temperature and a specific amount of time in the heat in order to reach full cure and create the properties it was designed to offer. Most powders cure around 390 degrees Fahrenheit on a 10-minute timer, however that schedule could change according to the needs and requirements of the manufacturer.
