COMPOSITIONS AND METHODS FOR PROTECTING COATINGS FROM THE DELETERIOUS EFFECTS OF EXPOSURE TO UV-C LIGHT

Coating compositions having a polymeric binder and a stabilizer composition including at least one of a UV absorber, a hindered amine light stabilizer (HALS), or an inorganic UV blocker are provided herein, wherein said coating compositions are more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating compositions in the absence of the stabilizer composition. Thus, a method of stabilizing a coating composition against the deleterious effects of UV-C (190-280 nm) light includes adding to the coating composition an effective amount of such a stabilizer composition, wherein the coating composition is made more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating composition in the absence of the stabilizer composition. Coated articles can be made from the coating composition, and methods of making stabilized coating films include adding the stabilizer composition to the coating composition.

Condensation reduction treatment

A method of treating a surface is provided. The method includes disposing a condensation reduction composition on the surface, thereby treating the surface to reduce formation of condensate and/or an amount of condensate thereon. The condensation reduction composition comprises a surface-active agent comprising an alkyl polyglycoside. The condensation reduction composition may further comprise a preservative, a pH control agent, and/or water. A treated surface prepared in accordance with the method is also provided. The method and treated surface prepared therewith are useful in reducing condensate and/or formation of condensate on surfaces, e.g. by reducing the number of condensate drops falling from the surface, increasing the rate of condensate evaporation on the surface, and/or increasing the rate of water absorption into or through the surface, e.g. upon or during exposure of the treated surface to a condensation condition.
