Q1: What types of microorganisms does AWC D-115I Biocide effectively control?
A: AWC D-115I Biocide is a broad-spectrum antimicrobial agent formulated to inhibit the growth of common bacteria, yeasts, and molds in industrial water-based systems. Its performance is particularly notable in challenging environments with moderate organic load and varying pH conditions.
Q2: In which industrial applications is AWC D-115I Biocide typically used?
A: This biocide is widely employed in metalworking fluids, latex emulsions, adhesives, coatings, and other water-miscible formulations where long-term microbial stability is required. It is especially suited for systems where compatibility with anionic and nonionic surfactants is essential.
Q3: How should AWC D-115I Biocide be dosed in a formulation?
A: Dosage depends on formulation requirements, system contamination level, and process conditions. It is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—and is often applied as a maintenance dose after initial shock treatment to sustain microbial control.
Q4: Is AWC D-115I Biocide compatible with common industrial additives?
A: Yes, AWC D-115I Biocide demonstrates good compatibility with many standard formulation ingredients, including corrosion inhibitors, defoamers, and emulsifiers. However, compatibility testing under actual use conditions is recommended prior to full-scale implementation.
