  • Patent number: 6555217
    Abstract: A self-supporting and self-adhesive molded article is described having a glass transition temperature of less than 10° C. and containing a binder and an aliphatic or cyoaliphatic nonionic surfactant. The binder may contain at least one addition polymer or addition copolymer. The article is redetachable from the material surfaces to which it may be adhered. Thus, the article may be attached, detached and reattached to a wall or cabinet surface and may have paper or other light weight, decorative material attached, detached and reattached to it. The detachment and reattachment process maybe repeated numerous times, particularly with intervening cleaning of the surface of the self-supporting and self-adhesive molded article.

  • Patent number: 5814684
    Abstract: The present invention provides an anti-fogging agent for the surface of a thermoplastic resin sheet which exerts the following excellent effects:(1) The effect of inhibiting fogging on the surface of the sheet due to the condensation of vapor can last over an extended period of time;(2) Excellent blocking resistance and coating stability make the anti-fogging surface less peelable in the procedure of heating it over a heating plate in a direct heating process so that it is formed into various shapes; and(3) The incorporation of a polyvalent alcohol having wetting properties in a predetermined amount provides excellent antistatic properties. The present invention provides an anti-fogging thermoplastic resin sheet treated with the foregoing anti-fogging agent.

  • Patent number: 5719244
    Abstract: Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. 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.

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.
