Dow Corning added silane (SiH4) to quaternary ammonia compounds (QACs or quats), to improve the adhesion of QUATs to a variety of surfaces. In doing so, Dow invented a durable class of antimicrobials that are effective against a range of unicellular organisms.

At least three private companies are primary in the manufacture of these silane quats known variously as SIQUATS, SIQACs and SILQUATS. Synthesis is typically conducted in a methanol, and water-based formulations range in stability depending on the dilution process and/or the presence of stabilizers and additives.


Literature shows efficacy of SIQUATS against a range of microbes.
