Problems solved by technology

Therefore, antibacterial and antifungal treatment must be carried out, and it is difficult for general-purpose epoxy coatings to be effectively applied under such conditions, and its antibacterial and antifungal effects are even worse, so it is not suitable for use in these humid environments
Therefore, antibacterial and mildew-proof coatings are urgently needed, and new challenges have also been proposed for the paint and coatings industry
