What is Zinc Umiguard Powder Marine Biocide?
Zinc Umiguard Powder Marine Biocide is a highly effective broad-spectrum bactericide, algicide and dry-film fungicide used to preserve industrial products against deterioration by fungi, yeast, algae and bacteria. The product is a zinc pyrithione powder specially formulated for use in certain water-based and 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
- Building materials (floor adhesives, sealants, caulks, etc.)
- Plastic products (PVC, polyurethane, rubber)
- Water-based mineral and pigment slurries
- Synthetic polymer emulsions and water-based adhesives
Advantages
- Broad-spectrum bactericide, algicide and fungicide — one product, multiple effects
- Particularly effective as a single-active dry-film preservative
- Non-specific mode of action, extremely unlikely to induce bacterial resistance
