RAL1018 Zinc yellow Pure polyester Powder Coating Paint for Household Electry Appliance
Pure polyester powder coating starts as granules of industrial polyester. The granules are mixed with coloring agents and chemicals and then fed into an extruder where the mixture is heated until it melts together. The extruder pushes out the mixed material where it is rolled flat and allowed to dry. The dry sheets are broken into chips and then ground into powder.
A thermoset coating undergoes a chemical reaction when heated, making the coating stronger than its constituent parts. A thermoplastic coating simply melts together during the curing process. While thermoplastic coverings are not as strong as thermoset, they are stronger than most conventional wet coverings.
1). No intoxication, no fire, no "three wastes" emissions and no other pollution problems
2). Raw material utilization is high, more than 99%.
3). Easy to automate operation, high production efficiency to reduce costs.
4). High coverage corners, with excellent resistance to chemical corrosion
5). Safety storage and convenience usage.
