Abstract
A process uses a water repellant material in order to enhance the water resistance of composite. The process begins with a saturated vegetable or animal fat triglyceride having a low iodine value. The triglyceride is melted to form a sprayable liquid. The sprayable triglyceride and a bonding agent are applied to the fibrous materials, preparatory to a press binding. Then, the sprayed fibrous 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.
