The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.Type: GrantFiled: November 13, 1996Date of Patent: February 17, 1998Assignee: National Starch and Chemical Investment Holding CorporationInventors: Rajeev Farwaha, William D. Currie, Robert W. Humphreys, John S. Thomaides

Patent number: 5629362Abstract: Photon-diffusive coating compositions contain a binder and a mineral containing at least about 65%, preferably at least about 75%, and most preferably at least about 85% to 90% silica, of which at least about 60%, preferably at least about 75% to 85% is in the crystal form of cristobalite, which has been reacted with sodium hydroxide. In typical embodiments, ground Klannerite.RTM. is reacted with sodium hydroxide in an aqueous slurry by the application of heat to just below the boiling point until the pH falls to below 12, and then a latex binder is added. Preferred binders comprise a mixture of polysaccharide resin and a latex binder; the polysaccharide resin is added, the mixture is neutralized somewhat, and then the latex binder is added. The viscosity of the final composition may be adjusted by adding water. Cured coatings exhibit good spectral reflectance and are useful in a variety of applications such as coating furnace interiors.Type: GrantFiled: May 31, 1995Date of Patent: May 13, 1997Assignee: Heatshield Technologies Inc.Inventor: Paul R.
