IMPROVED POLYCARBOXY/POLYOL FIBERGLASS BINDER OF LOW PH

摘要

Provided is a fiberglass binder which contains a polycarboxy polymer and a polyol, with a pH of the binder being no greater than 3.5. It is further preferred that the polycarboxy polymer has a molecular weight of less than 10,000, and more preferably about 5000 or less. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus polyol is preferably triethanolamine. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus-containing organic acid. The resultant binder, particularly when used in preparing fiberglass products, provides minimal processing difficulties and a product with excellent recovery and rigidity.
