What is Oamiguard Z40X Dry-film Mildewcide?
Oamiguard Z40X is a highly effective broad-spectrum biocide and dry-film mildewcide used to preserve industrial products against deterioration by fungi, yeasts, algae and bacteria. The product is an aqueous dispersion of zinc pyrithione, specially formulated to avoid the grey-blue discoloration caused by the interaction of soluble iron with the zinc active substance in certain water-based coating formulations, ensuring the stability of water-based coating systems.
Applications
- Architectural and industrial paints and coatings
- Construction materials (flooring adhesives, sealants, grouts, cement slurries and joint compounds)
- Construction materials (ceilings, ceiling tiles, walls and interior partitions)
- Water-based mineral and pigment slurries
- Synthetic polymer emulsions
- Water-based adhesives
Advantages
- Broad-spectrum antibacterial, mildewcide and algicide, multiple effects in one product
- Avoids the grey-blue discoloration caused by the reaction of soluble iron with the zinc active substance
- Non-specific mode of action, extremely unlikely to develop bacterial resistance
