GPSG-10DL is a high-performance silver glass–based anti-microbial additive supplied as a free-flowing powder, engineered for durable and long-term microbial protection in industrial materials. The active silver component is permanently embedded within a chemically stable glass matrix, enabling a controlled and sustained release of silver ions over the service life of the treated product.
This mechanism helps inhibit the growth of bacteria, fungi, mold, and mildew on surfaces, even under humid and microbe-prone conditions. Unlike conventional organic biocides, GPSG-10DL offers non-leaching performance, low volatility, and excellent thermal stability, making it suitable for high-temperature processing and demanding applications.
GPSG-10DL is designed for use in plastics, polymer compounds, coatings, sealants, and construction materials, where long-lasting hygiene, odor control, and resistance to microbial-induced degradation are required. Its inorganic nature ensures long service life, formulation stability, and compatibility with a wide range of systems, providing manufacturers with a reliable antimicrobial solution for modern industrial applications.
