Thermoplastic powder coating. Thermoplastic powder coatings began to appear in 1950. It melts at the spraying temperature and solidifies to form a film when cooled. Due to the simple processing and spraying method, the powder coating only needs to be heated and melted, leveled, cooled or extracted and solidified to form a film, without requiring a complicated curing device. Most of the raw materials used are common polymers on the market, which can meet the performance requirements under most conditions. However, there are certain deficiencies, such as high melting temperature, low coloring level, and poor adhesion to metal surfaces. Nevertheless, commonly used thermoplastic powder coatings still exhibit some unique properties, among which polyolefin powder coatings have excellent solvent resistance; polyvinylidene fluoride coatings have outstanding weather resistance; polyamides have excellent wear resistance; poly Vinyl chloride has a good price / performance ratio; thermoplastic polyester powder coatings have the advantages of beautiful appearance and high artistry. These characteristics make thermoplastic powder coatings occupy a large proportion in the coating market.
