What is Oamiguard K150 Stable Preservative?
Oamiguard K150 is a highly effective, broad-spectrum, stable preservative used to protect water-based industrial products from bacteria, yeasts and molds. It is a combination of chloromethylisothiazolinone (CMIT) and methylisothiazolinone (MIT) with excellent compatibility for systems prone to demulsification, keeping emulsions and water-based coating systems stable, and is particularly effective as a single active biocide preservative.
Applications
- Architectural and industrial paints and coatings
- Building materials (floor adhesives, fillers, sealants, cement slurries, joint compounds)
- Base materials (polymer emulsions, pigment dispersions)
Advantages
- Broad-spectrum and highly effective against bacteria, yeasts and molds
- Excellent compatibility with systems prone to demulsification, keeping emulsions and water-based coating systems stable
- Non-specific mode of action; bacterial resistance extremely unlikely
