QM Preservative(BIT‑20 Liquid)
QM Preservative (BIT-20 Liquid) is a broad-spectrum antimicrobial agent specifically formulated for coating systems. It effectively inhibits bacteria and yeasts, and is suitable for formulations with pH 6–10. The recommended dosage is 0.1%–0.3%, to be added during the grinding or dispersion stage at temperatures below 60°C. Free from chlorine and formaldehyde releasers, this low-odor product is an ideal preservative for low-VOC latex paints, preventing issues such as bloating, odor development, and viscosity loss during storage. It is widely used in interior and exterior latex paints, water-based industrial coatings, and various architectural coating products.
