Product Details

Antimicrobial Surface Treatments
Pre-painted coils for hygienic environments incorporate antimicrobial additives:

Silver-ion zeolites: 1.5-3.0% loading, releasing Ag⁺ ions disrupting microbial metabolism
Quaternary ammonium silanes: Covalently bonded to resin, providing non-leaching protection
Photocatalytic TiO₂: Nano-coated surfaces generating ROS under UV light

Testing per ISO 22196 confirms >99.9% reduction against E. coli and S. aureus within 24 hours. The additives withstand 500 cleaning cycles with bleach solutions. Hospital applications show 45% lower bacterial colonization versus standard coatings. The technology meets EPA and EU Biocidal Products Regulation (BPR) standards.
