  • Phenol/formaldehyde fiberglass binder compositions exhibiting reduced emissions
    Patent number: 5578371
    Abstract: Fiberglass binder solutions based on phenol/formaldehyde resins emit lower formaldehyde emissions when a water soluble bisulfite formaldehyde scavenger is added to the binder prior to spraying onto fiberglass. Sodium bisulfite and ammonium bisulfite in amounts of from 4 to 6 percent based on binder solids can reduce formaldehyde emissions by c.a. 50 percent. The fiberglass products prepared from the binders exhibit no significant loss of physical properties as compared to conventional binders.
