ABSTRACT:
Aqueous dispersions of heat-hardenable phenolic resins are disclosed. They are characterized by excellent stability and by a low Pollution Index; they are capable of being infinitely diluted with water, and they are especially desirable for use in applications wherein mineral fibers are sprayed with the aqueous dispersions and subsequently formed into mineral fiber batts.
