ADDYBAT LD1540
ADDYBAT LD1540 is an antibacterial product developed for antimicrobial powder coatings with high temperature resistance and low volatile content requirements. It is a high-activity broad-spectrum antibacterial agent that meets the latest green coating technical standards. Blue Shield LD1540 is an ultra-fine powder specially formulated to avoid discoloration due to interaction with various elements that may be present in some coating formulations. LD1540 is also widely used in plastic products anti-bacterial and anti-mildew (including PP\PE\Nylon and other engineering plastics).
Advantages:
Effectively inhibit the growth of Escherichia coli, Staphylococcus aureus and yeast on the paint film.
Effectively inhibit the growth of mold and algae.
