Metallic pigmented powder coating, composed of metallic pigments and coating particles, provides coatings with metal shine and functional protection, while causes much less emission of organic solvents, unlike the traditional paint. The greatest challenge of the manufacturing step is binding the two incompatible ingredients together. However, the present industrial binding method, thermal bonding, has some inherent issues, such as pre-curing, pigment bending and high-temperature bonding. Hence, in the present work, a novel approach, microwave bonding, was studied and tested to address these shortcomings. Aluminum flakes were bonded with three types of powder coatings: polyester, hybrid, and polyvinylidene fluoride (PVDF). Microwave bonding shows a more stable metal shine over the non-bonding, obtains a lower bonding temperature than the glass transition temperature, and has a much higher heating rate ($\sim$17 °C/min) over the thermal bonding method. Therefore, microwave bonding is trusted to have great potential to produce coatings with highly stable metal shine efficiently.

金属颜料粉末涂料由金属颜料和涂料颗粒组成，可为涂料提供金属光泽和功能保护，同时减少有机溶剂的排放，这与传统涂料不同。制造步骤的最大挑战是将两种不相容的成分粘合在一起。但是，目前的工业粘合方法，即热粘合，具有一些固有的问题，例如预固化，颜料弯曲和高温粘合。因此，在本工作中，研究并测试了一种新颖的方法，即微波键合，以解决这些缺点。铝片用三种类型的粉末涂料粘合：聚酯，混合涂料和聚偏二氟乙烯（PVDF）。微波粘结显示出非粘结上更稳定的金属光泽，$〜$17°C / min）。因此，人们相信微波键合具有巨大的潜力，可以有效地生产出具有高度稳定的金属光泽的涂层。
