What is Omiguard KF300 Preservative?
Omiguard KF300 is a highly effective broad-spectrum bactericidal preservative used to protect water-based industrial products against bacteria, yeasts and molds. The product is a blend of chloromethylisothiazolinone, methylisothiazolinone and a slow-release aldehyde, ensuring the stability of water-based coating systems.
Applications
- Architectural and industrial paints and coatings
- Building materials (floor adhesives, joint fillers, sealants, etc.)
- Base materials, polymer emulsions, pigment dispersions
Advantages
- Broad-spectrum bactericidal, effective for both in-can and vapor-phase preservation
- Non-specific mode of action, extremely unlikely to cause bacterial resistance
- Blended system, highly adaptable
