Abstract
A stain-treated substrate comprising an extremely thin coating for stain protection. The stain-treated substrate includes substrate material and the extremely thin coating include a molecular layer of organosilane 3-(trimethoxysilyl) propyldimethyl octadecyl ammonium chloride covalently bonded to the surface of the substrate material. The substrate material can include a wide variety of materials including tile, ceramic, glass, stone and marble and can optionally be used in conjunction with a grout mixture including a diluted organosilane mixture.
Claims8
An apparatus comprising a substrate and a coating for stain protection, the apparatus comprising:
- the substrate;
- and
- the coating comprising a molecular layer of organosilane 3-(trimethoxysilyl) propyldimethyl octadecyl ammonium chloride wherein the coating is covalently bonded to the substrate, wherein the coating is created by:
- preparing a diluted solution of organosilane 3-(trimethoxysilyl) propyldimethyl octadecyl ammonium chloride in a concentration range of between 0.72% and 3.6%;
- heating and maintaining the substrate to an above-room temperature comprising a temperature of between 100 degrees Celsius and 120 degrees Celsius;
- applying the water-diluted solution to the substrate;
- curing the substrate and water-diluted solution until dry and polymerized at the above-room temperature;
- and
- removing excess polymerized solution from the substrate.
