Low Odor Binder for Molded Fiberglass

Molded automotive headliners are composed of a matrix of glass fibers and an organic thermosetting binder. Conventional fiberglass binders for applications such as automotive headliners contain nitrogen based formaldehyde scavenging compounds to reduce the release of highly irritating formaldehyde fumes in the product forming and molding steps. The scavenging compounds employed can result in the formation and deposition of objectionable amine compounds, specifically trimethylamine, in the finished products. Since the release of highly odorous compounds in a vehicle interior is very undesirable, a new fiberglass binder has been developed for molded products that eliminates the root cause of objectionable odors.
