Odor free molding media having a polycarboxylic acid binder

Abstract

A polycarboxylic acid based binder material used in fiberglass media products. The binder material eliminates the odor and emissions complaints associated with urea phenol formaldehyde based binder systems and has a significantly longer shelf life. The polycarboxylic acid based binder material has a loss of ignition value of between approximately 15 and 20 percent is applied in a one-step process. Preferably, the binder material comprises a polycarboxylic acid binder, and more preferably a polyacrylic acid binder. The polycarboxylic acid binder is crosslinked with either glycerol or triethanol amine. A silane-coupling agent is typically added at approximately 0.1 percent based on binder solids to improve adhesion of the binder to the fiberglass wool reinforcement.
