What is Oamiguard Z40 Dry-film Mildewcide?
Oamiguard Z40 is a highly effective, broad-spectrum bactericide and dry-film mildewcide used to preserve industrial products against deterioration caused by fungi, yeast, algae and bacteria. The product is an aqueous dispersion of zinc pyrithione, specially formulated to avoid the grey-blue discoloration caused by the interaction between soluble iron and zinc active substances in certain water-based coating formulations, ensuring the stability of water-based coating systems.
Applications
- Architectural and industrial paints and coatings
- Building materials (flooring adhesives, caulks, sealants, grouts and joint compounds)
- Building materials (ceilings, ceiling tiles, walls and interior partitions)
- Water-based mineral and pigment slurries
- Synthetic polymer emulsions
- Water-based adhesives
Advantages
- Broad-spectrum bactericidal, mildew and algae protection in a single product
- Avoids grey-blue discoloration caused by the reaction between soluble iron and zinc active substances
- Non-specific mode of action, extremely unlikely to induce bacterial resistance
