Abstract
Described herein is a method of forming a reflective article comprising applying an anti-fog composition to a major surface of a reflective substrate, the anti-fog composition comprising an anti-fog agent and a liquid carrier and having a solid's content between about 15 wt. % to about 35 wt. % based on the total weight of the anti-fog composition, and subsequently heating the reflective substrate to a temperature of about 80° F. to about 325° F. for a drying period, and wherein the liquid carrier comprises water and a hydroxyl-containing component.
Claims28
A method of forming a reflective article comprising:
- a) applying an anti-fog composition to a major surface of a reflective substrate, the anti-fog composition comprising an anti-fog agent and a liquid carrier and having a solid's content between about 10 wt. % to about 30 wt. % based on the total weight of the anti-fog composition;
- b) heating the reflective substrate to a temperature of about 120° F. to about 325° F. for a drying period;
- and
- wherein the liquid carrier comprises a hydroxyl-containing component.

A method of forming a reflective article comprising:
- a) spray applying an anti-fog composition to a major surface of a reflective substrate, the anti-fog composition comprising an anti-fog agent, silica, and a liquid carrier, the liquid carrier that includes a hydroxyl-containing component comprising:
- methanol;
- ethanol;
- and
- diacetone alcohol;
- b) heating the reflective substrate to an elevated temperature to evaporate at least a portion of the liquid carrier from the major surface of the reflective substrate;
- wherein the hydroxy-containing component is present in an amount ranging from about 60 wt. % to about 80 wt. % based on the total weight of the anti-fog composition.

A composition for spray-applying to a glass substrate, the composition comprising:
- an anti-fog agent;
- silica;
- liquid carrier comprising:
- an alcohol component;
- an aromatic compound;
- and
- wherein the anti-fog coating composition has a solids content ranging from about 15 wt. % to about 30 wt. % based on the total weight of the anti-fog coating composition, and the alcohol component comprises at least one of methanol, ethanol, butanol, diacetate alcohol, and 1-methoxy-2-propanol.
