CAVINON Antibacterial and Antifungal Agent
CAVINON is a composite antifungal antibacterial agent developed by Toagosei. It combines the long-lasting performance of inorganic antifungal agents with the powerful antibacterial and antifungal activity of organic agents. It provides excellent, durable inhibition of both mold and bacteria while maintaining a high level of safety.
Features
•High heat resistance for resin compounding
•Sustained-release action maintains antifungal performance
•Excellent water and chemical resistance
•Effective against a wide range of molds
•Product grades with antibacterial performance available
