Compared with other types of powder coatings, polyurethane powder coatings have the following characteristics: (1) When melted and leveled, the melt viscosity is low, especially the sealing agent does not have any chemical reaction before unsealing, so that the powder coatings have enough leveling time, coating Membrane leveling is good.
Compared with other types of powder coatings, polyurethane powder coatings have the following characteristics: (1) When melted and leveled, the melt viscosity is low, especially the sealing agent does not have any chemical reaction before unsealing, so that the powder coatings have enough leveling time, coating Membrane leveling is good. The realization of the new inner-closed uretdione curing agent technology makes the air pollution of this powder coating almost zero; (2) it has good adhesion to the coated object and does not need primer; (3) the preparation range of the coating is wide and can be Prepare coatings with different performance requirements and curing speeds; (4) The physical and mechanical properties and chemical resistance of the coating film are good. However, when the polyurethane powder coating is baked, it will release the sealing agent and produce peculiar smell.
