Epoxy coatings are extensively used for the interior and exterior coatings of shipping containers, including workshop primers, interior and exterior primers, intermediate paints, and interior topcoats. These epoxy coatings have the functions of corrosion resistance, wear resistance, scratch resistance, impact resistance, and maintaining good adhesion to the substrate. Meidong Biotechnology has also developed a series of water-based epoxy curing agents for the maritime container industry, which are developed to adapt to different production line conditions of container factories in conjunction with container coating customers, providing guarantees for various types of containers.
