Use of aldehyde scavengers in interior building products

Abstract

A coating for application to the surface of an interior building product comprises: a resin formulation such as a melamine formaldehyde resin characterized by its ability to strengthen the interior building product when applied as a coating to the building product; and an aldehyde scavenger selected from the group consisting of; tetraethylene pentamine, propionamide, caprolactam, ammonium hydroxide, sodium bisulfate, sodium metabisulfite, ammonium primary phosphate, ammonium secondary phosphate, a combination of ammonium primary phosphate and ammonium secondary phosphate, a combination of ammonium primary phosphate, ammonium secondary phosphate and a sulfite, a polyvinyl alcohol; adipic dihydrazide and a combination of a polyvinyl alcohol and adipic dihydrazide.

Description

[0001]This application claims the benefit of U.S. provisional patent application Ser. No. 61 / 510,109, filed Jul. 21, 2011.FIELD OF THE INVENTION[0002]The present invention in general concerns coatings that are applied to interior building products, such as ceiling tile for example, wherein the coatings include an aldehyde scavenger that possesses the ability to tie-up any aldehydes, including formaldehyde, and / or other volatile organic compounds that may tend to be emitted from the basic interior building products themselves and / or the coatings.BACKGROUND OF THE INVENTION[0003]Many interior building products such as ceiling tiles, fiber panels and gypsum wallboard and other types of wallboard, for example, following their installation, can exhibit a tendency to emit aldehyde, including formaldehyde, vapors and / or other kinds of volatile organic compounds (“VOCs”) to their surroundings. The sources of the aldehydes and other VOC's may reside in the basic interior building product its...

AI Technical Summary

Benefits of technology

[0008]According to one aspect, the present invention concerns a coating for application to the surface of an interior building product, including a resin formulation characterized by its ability to strengthen the interior building product when applied as a coating to the building product together with an aldehyde scavenger.

Problems solved by technology

The emission of the aldehydes and other VOCs can be undesirable and efforts can be undertaken to avoid their release into their surroundings because of their deleterious effects on human and animal health, as well as on the general comfort of humans and animals exposed to the emissions.
