What is Oamiguard Z50 Antibacterial Agent?
Oamiguard Z50 dispersion is a highly effective broad-spectrum antibacterial agent that effectively protects products against deterioration by molds, yeasts, algae and bacteria. The product is an aqueous dispersion of a zinc hydroxypyridinethione chelate, namely zinc 2-pyridinethiol-1-oxide, commonly known as zinc pyrithione. Oamiguard Z50 dispersion has a low viscosity and excellent dispersibility and flowability, making it easier to incorporate into product systems.
Applications
- Architectural and industrial paints and coatings
- Construction materials (flooring adhesives, sealants, grouts, cement slurries, joint compounds)
- Water-based mineral and pigment slurries
- Synthetic polymer emulsions
- Water-based adhesives
- Textiles (apparel and furnishing products)
- Control of mold and bacteria in plastic products (carpets, carpet backing, curtains, foam mattresses, sports flooring and mats, footwear, sponges)
Advantages
- Broad-spectrum antibacterial and mildewcide, effective against molds, yeasts, algae and bacteria
- Low viscosity, excellent dispersibility and flowability, easy to incorporate into product systems
- Non-specific mode of action, extremely unlikely to develop bacterial resistance
Physical & Chemical Parameters
| Composition | Aqueous dispersion of zinc 2-pyridinethiol-1-oxide (zinc pyrithione) |
| Appearance | Off-white liquid |
| pH (5% slurry in water, 20 ℃) | 6.5 - 8.5 |
