Problems solved by technology

Therefore, anti-corrosion and anti-bacterial treatment must be carried out, and it is difficult for general-purpose epoxy coatings to be effectively applied under such conditions, and its anti-bacterial effect is even worse, so it is not suitable for application in these humid environments
Therefore, antibacterial coatings are urgently needed, and at the same time, new challenges have been proposed for the paint and coatings industry.
