Widely used as a biocidal additive in coatings, textiles, and construction materials due to its strong antimicrobial properties. It effectively inhibits the growth of bacteria, fungi, and algae on surfaces, making it ideal for use in hospitals, laboratories, and humid environments. When incorporated into paints or sealants, it provides long-term protection against microbial degradation and odor formation. Also used as a coupling agent in composite materials, enhancing the compatibility between organic polymers and inorganic surfaces. Its reactive silane group allows for covalent bonding to substrates like glass, metal, and concrete, ensuring durable and permanent antimicrobial action. Commonly applied in marine coatings to prevent biofouling and in sanitary fixtures to maintain hygiene.
