Q1: What is the primary mechanism of antimicrobial action for SILVADUR 930 FLEX?
A: SILVADUR 930 FLEX utilizes a controlled-release silver ion technology, where silver ions are gradually released from a polymer-bound complex upon contact with moisture or microbial activity, providing durable and long-lasting protection against bacteria, fungi, and odor-causing microorganisms.
Q2: Is SILVADUR 930 FLEX suitable for use in flexible or elastomeric coatings and adhesives?
A: Yes — as indicated by the “FLEX” designation, this grade is specifically engineered for compatibility with soft, stretchable, and low-Tg polymer systems, including acrylics, polyurethanes, and styrene-butadiene formulations, maintaining efficacy without compromising film integrity or flexibility.
Q3: How does SILVADUR 930 FLEX differ from other SILVADUR biocides like 900 or 920?
A: SILVADUR 930 FLEX is formulated to offer enhanced compatibility with flexible matrices and improved shear stability during high-solids dispersion or high-speed mixing processes, distinguishing it from earlier grades optimized primarily for rigid or architectural coatings.
Q4: Can SILVADUR 930 FLEX be used in water-based systems?
A: Yes — it is designed for stable incorporation into aqueous dispersions and emulsions, including latex-based paints, textile finishes, and hygiene-related coatings, with good shelf-life stability under typical pH and temperature conditions.
