USE OF POLYACRYLIC ACID AND OTHER POLYMERS AS ADDITIVES IN FIBERGLASS FORMALDEHYDE BASED BINDERS.

摘要

A process for preparing binder-coated fiber-glass products employs as a binder aqueous polymer system comprising a nitrogenous formaldehyde resin such as a urea-extended alkaline phenol/formaldehyde resole together with an acidic polyacrylate which cocure to form a thermoset polymer while synergistically reducing ammonia emissions which normally occur during cure of the nitrogenous formaldehyde resin. The polymer system may be used in applications other then fiberglass where reduced emissions are desired.
