Overview

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
