Documented Uses

• Used as a preservative for paints (in can), coatings, textiles (i.e. footwear, apparel, upholstery, and carpet), sails, ropes, fire hose, concrete additives, roofing materials, filter media, polyurethane foam, cellulose products, and cleaning buffers, and as a fungicide for hard non-porous surfaces and garbage cans; [Reference #1]
• Painting (Pigments, Binders, and Biocides) [Category: Paint]
• Using Disinfectants or Biocides [Category: Clean]
• Cement Producing [Category: Industry]
• Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
• In liquid-crystal displays, clarity and permanence of image is enhanced if the display can be oriented parallel or perpendicular to the substrate. Oxide surfaces treated with dimethyloctadecyl-3-trimethoxysilylpropylammonium chloride ... tend to orient liquid crystals perpendicular to the surface.
