ABSTRACT:
Disclosed is a low formaldehyde emission coating from formaldehyde-based resins that can be applied to a panel for reducing sag and enhancing the strength of the panel. Formaldehyde emissions are reduced by the inclusion of polymeric formaldehyde reactive materials comprising a polyamide scavenger into the coating formula. These formulations are useful as coatings or binders.
