Powder Thermoplastic
Aug 17, 2017

    Powder coating refers to a new type of solvent-free 100% solid powder-like coating. With solvent-free, pollution-free, recyclable, environmental protection, energy saving and resources, reduce labor intensity and coating mechanical strength of high characteristics. Powder coating is completely different from the general coating of the form, it is in the state of fine powder exist. Because the solvent is not used, it is called powder coating. The main characteristics of powder coatings are: harmless, high efficiency, saving resources and environmental protection characteristics. It has two main categories: Thermoplastic powder Coatings and thermosetting powder coatings.Powder
    Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide series, Cellulose series, polyester system. Thermosetting powder coatings are composed of thermosetting resins, hardener, pigments, fillers and auxiliaries. Thermosetting powder coatings include: Epoxy system, polyester system, acrylic resin system. Disadvantages: Uneven powder on the corners, after curing coating defects difficult to cover up, curing conditions high.Powder
    The classification standard is many, the name of each kind of powder on the market is uneven. According to the properties of film-forming materials are divided into two main categories: Thermoplastic powder Coatings and thermosetting powder coatings. Or the appearance of film-forming materials are divided into: extinction type, high light type, fine art type. can also be divided into the use of the environment: indoor and outdoor type of two major categories.Powder
    Hot-solid powder coating refers to thermosetting resin as a film material, adding the crosslinking reaction of curing agent after heating can form a hard coating of insoluble texture. The coating is not as soft as the thermoplastic coating, and can only decompose when the temperature is higher. Because the resin used in thermosetting powder coatings is a prepolymer with lower polymerization degree, the molecular weight is low, so the coating leveling is good, has the good adornment, and the low molecular weight prepolymer after curing, can form the reticular cross-linked macromolecule, thus the coating has the good antiseptic and the mechanical performance. Therefore, the development of thermosetting powder coatings is particularly rapid.Powder
