Antibacterial Glass Powder
Powder glass with high antibacterial properties
ZF-0 and DL-7900 are a new type of antibacterial glass powder, with zinc as their main component. Notably, DL-7900 offers higher antibacterial capacity compared to traditional antibacterial glass that is primarily composed of silver, allowing for a reduced amount of Antibacterial Glass Powder to be added to the resin.
