Quaternary Silane 60% in IPA GPQS-60

Quaternary Ammonium Silane (QAS) Antimicrobial Concentrate | 60% Active

GPQS 60 is a high-performance Quaternary Ammonium Silane (QAS) antimicrobial concentrate, engineered with 60% active organosilane content and stabilized in an isopropyl alcohol (IPA) carrier for efficient delivery and formulation compatibility. Unlike conventional antimicrobial agents that rely on migration or leaching, GPQS 60 utilizes an advanced silane-based surface bonding mechanism to deliver long-lasting antimicrobial protection.

Upon application, the silane groups undergo hydrolysis and condensation, forming permanent covalent bonds with the substrate surface. This reaction creates a durable, cross-linked molecular network that becomes an integral part of the treated surface rather than a temporary coating. The resulting surface contains a dense layer of positively charged quaternary ammonium structures, providing continuous antimicrobial functionality without altering the appearance, texture, or breathability of the material.

GPQS 60 delivers antimicrobial performance through a non-leaching, contact-active kill mechanism. Negatively charged microorganisms—including bacteria, fungi, algae, and odor-causing microbes—are electrostatically attracted to the surface. Upon contact, the long-chain alkyl groups of the quaternary ammonium moiety mechanically disrupt microbial cell membranes, leading to rapid cell inactivation. Since the active chemistry is chemically bonded and not consumed, antimicrobial efficacy remains effective for extended periods, limited only by physical abrasion of the surface.

Designed for broad industrial compatibility, GPQS 60 is suitable for incorporation into coatings, sealants, textiles, polymers, construction materials, and specialty cleaning formulations. In coatings and sealants, it helps prevent microbial growth, film deterioration, and surface discoloration. In textiles and polymer systems, it provides built-in odor control and protects materials from fungal and bacterial degradation. GPQS 60 is also widely used in hygiene-critical environments, including healthcare facilities, food-processing areas, and public infrastructure.

By selecting GPQS 60, formulators gain a durable, non-migrating, and environmentally responsible antimicrobial solution that meets the performance, longevity, and compliance expectations of modern industrial and biosafety-driven applications.
