    Abstract: The invention is drawn to a method of coating a glass fiber textile comprising the following steps: —Preparing an aqueous coating composition comprising (a) 5 to 95% by weight, with respect to the total weight of (a) and (b), of a synthetic polymer or oligomer dissolved or dispersed in the aqueous coating composition, and (b) 5 to 95% by weight, with respect to the total weight of (a) and (b), of a dextrin exhibiting a weight-average molecular weight ranging from 250 000 to 2 000 000 Da and a solubility, measured according to a test A, ranging from 50 to 85%, —Applying said aqueous coating composition to a glass fiber textile, thereby obtaining a wet-coated glass fiber textile, —Submitting the wet-coated glass fiber textile to a step of drying and/or curing thereby obtaining a glass fiber textile coated with a water-insoluble polymer coating.

    Abstract: A method of making a glass mat includes providing an assembly of glass fibers, applying a binder composition to the assembly of glass fibers, wherein the binder includes an organic resin, and curing the binder composition while dimensionally constraining the assembly of glass fibers. Dimensional constraining includes directly contacting a first major surface and a second major surface of the assembly of glass fibers between two substantially parallel surfaces. Further provided is a glass mat that includes an assembly of glass fibers, wherein the assembly of glass fibers are substantially randomly oriented with a tensile anisotropy of less than about 6 in any two directions. The glass mat has a decreased surface roughness and a decreased caliper compared to an equivalent glass mat having an assembly of naturally packed glass fibers with an equivalent fiber diameter size.
