Compared with solvent-based coatings, water-based coatings have the following characteristics:
(1) Using water as a solvent saves a lot of resources; eliminates the risk of fire during construction; reduces air pollution; only uses a small amount of low-toxic alcohol ether organic solvents to improve the working environment. Generally , the organic solvent of water-based paint (accounting for paint) is between 10% and 15%, but the current cathodic electrophoretic paint has dropped to less than 1.2%, which is effective for reducing pollution and saving resources.
(2) Water-based coatings can be directly coated on wet surfaces and in humid environments; they have good adaptability and strong coating adhesion.
(3) The coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvents.
(4) The electrophoretic coating film is uniform, smooth, and has good flattening properties; the inner cavity, welds, corners, and edges can coated with a certain thickness of the coating film, which has good protection; the electrophoretic coating film has Better corrosion resistance, the salt spray resistance of thick film cathodic electrophoretic coating can reach up to 1200h.
