Anti-Microbial Thermosetting Powder Coating

Anti-Microbial powder coating prevents the spread of dangerous micro-organisms across a wide range of application and suppress the growth of mold and bacteria. Anti-bacterial finishes are available in all combinations like epoxy, epoxy polyester and polyester versions. Anti-bacterial powder coating should be regularly washed with warm water and mild liquid detergent followed by a fresh water rinse to maintain the attractive appearance and aesthetics of the powder cured film. The use of abrasive cleaners is not recommended nor is the use of active organic solvents. Superior finish and application time makes it an ideal choice for White Goods & Furniture, Pharmaceutical equipment and industry, inlcuding air conditioning ventilation systems.
