Abstract
A method of enhancing water resistance of composites uses a water repellant material which may be applied toward and other fibrous vegetable materials. The method begins with a saturated vegetable or animal fat triglyceride having a low iodine value. The triglyceride is rendered in a form which may be a fine powder, an emulsion, or a dispersion in a liquid. The sprayable triglyceride and a bonding agent are applied to the fibrous materials, preparatory to a press binding. There, the sprayed material is subjected to a hot press cycle in order to form a bonded fibrous composition. The low Iodine Value triglyceride may be selected from a group including hydrogenated vegetable oil, palm oil, stearine, winterized low IV fractions, soy stearine, animal fat, hydrogenated animal fat, and fractionated fats or blends of these materials.
