Title:
RINSE AID SURFACE COATING COMPOSITIONS FOR MODIFYING DISHWARE SURFACES
Document Type and Number:
WIPO Patent Application WO2002060998
Kind Code:
A3
Abstract:
Rinse aid materials for coating, coating compositions, methods and articles of manufacture for use in automatic dishwashing appliances comprising a nanoparticle system or employing the same to impart surface modifying benefits for all types of dishware surfaces are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of rinse aid surface coating compositions, methods and articles of manufacture that create multi-use benefits to modified dishware surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that include at least one of the following improved surface properties: wetting and sheeting, uniform drying, anti-spotting, anti-staining, anti-filming, self cleaning, and durability benefits, relative to dishware surfaces unmodified with such nanoparticle systems. In some embodiments, actively curing the rinse aid surface coating composition on the dishware surfaces, including, but not limited to by radiative heating the air surrounding the dishware surface with the coating thereon can be used to increase the durability of the dishware surface coating.
