SR-B Series Preservatives

       The SR-B Series is a highly effective blended preservative that delivers true synergistic activity and offers numerous advantages over conventional CIT/MIT blends and pure BIT biocides. These advantages include synergistic activity, temperature and pH stability, no restrictive hazard labeling, broad-spectrum microbial control, and freedom from AOX and formaldehyde. Primary applications include polymer emulsions, adhesives, paints and coatings, pigment and mineral slurries, and other alkaline water-based systems.
       The SR-B Series consists of widely used, efficient, environmentally friendly water-based biocidal preservatives. It protects coatings against bacteria, fungi, and algae and provides long-lasting antifungal and antialgal protection on coating surfaces. It prevents microbial contamination in household and personal-care products, supporting safer and milder formulations. It also protects metalworking fluids from microbial contamination and addresses resulting problems such as odor, discoloration, agglomeration, pipe blockage, oil-phase separation, loss of lubrication and corrosion protection, and pH decline.
       The SR-B Series also provides long-term protection for building-material additives and construction auxiliaries, preventing discoloration, odor, and swelling caused by bacteria and fungi and preserving product performance.
