Coated and uncoated fibrous mats, and laminates containing the mat, having
one or more surfactants on the fibers and binder holding the fibers
together in only a portion of the thickness of the mat are disclosed. The
mat contains a major portion of non-cellulosic fibers and a minor portion
of cured resinous binder with the most typical fibers being glass fibers.
The surfactant on the surface of the fibers causes a slurry or other
liquid applied to the mat in a later process to form a board or laminate
like faced gypsum board, a faced foam board, etc. to uniformaly penetrate
the mat to the desired distance. Also disclosed are methods of applying
the surfactant(s) to the hot, coated or uncoated, mat soon after the
coated or uncoated mat exits a drying oven used in the process of making,
or coating, the mat
