Description

technical field [0001] The invention relates to the field of coatings, in particular to a single-component high-adhesion epoxy-modified acrylic anti-corrosion coating. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. The current commercially available anti-corrosion coatings for automobile chassis have the following disadvantages: 1. Harmful to the environment; 2. Poor chemical resistance; 3. Limited thermoplastic performance; Brittle cracks; 5. Poor adhesion, limited use, etc. Contents of the invention [0003] In view of the deficiencies in the above-m...
