What is Oamiguard Z98 Antibacterial Agent?
Oamiguard Z98 is a highly effective broad-spectrum biocide, algicide and dry-film mildewcide used to preserve industrial products against deterioration by fungi, yeasts, algae and bacteria. The product is a zinc pyrithione powder specially formulated for certain water-based/oil-based coating formulations, ensuring the stability of water-based coating systems and extending the service life of plastic products.
Applications
- Architectural and industrial paints and coatings
- Construction materials (flooring adhesives, sealants, etc.)
- Plastic products (PVC, polyurethane, rubber)
- Water-based mineral and pigment slurries
- Synthetic polymer emulsions, water-based adhesives
Advantages
- Broad-spectrum antibacterial, algicide and mildewcide, multiple effects in one product
- Particularly effective as a single-active dry-film preservative
- Non-specific mode of action, extremely unlikely to develop bacterial resistance
