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.
