1. A stabilized aqueous solution of silanol quaternary ammonium compound (SQAC) resistant to premature polymerization comprising:

  • a mixture formed from an anhydrous SQAC defined as 3-(trimethoxysilyl) propyl-N-octadecyl-N,N-dimethyl ammonium chloride and an essential oil selected from the group consisting of cedarwood oil and pine tree oil, a ratio of a weight of the essential oil to the weight of the SQAC is between about 0.2 and about 0.5; and

    a balance of demineralized water to a desired aqueous concentration, whereby the selected essential oil evaporates during a coating or curing of a substrate, allowing a generation of homopolymer crosslinking of a silanol group defined by the SQAC, thereby providing a highly water and solvent insoluble coating on the substrate.
