ROCIMA™ 550 Microbiocide is an aqueous-based microbiocide which delivers superior performance as a preservative in a variety of industrial applications. ROCIMA 550 is used for preservation of polymer latices, adhesives, tackifiers, mineral dispersions, building materials and paint and coatings.
The active ingredient in this product is 2-methyl-4-isothiazolin-3-one.
Features & Benefits of ROCIMA 550
- Chemically stable in high pH systems
- Provides an excellent alternative to Benzisothiazolone (BIT)
- Physically compatible with polymer emulsions: no negative influence on the physical/chemical performance parameters on the finished products
- Broad-spectrum efficacy against gram-positive and gram-negative bacteria, mold, and yeast
- Low VOC
- Does not contain or release formaldehyde
- Free from metal salts: Will not form a coagulum
- Fully water-soluble: Stays in the aqueous phase where biological control is needed
- Environmentally safe: Does not contain active halogens, does not contribute to AOX, and is biodegradable below microbicidal threshold concentrations
