Claim:
1. A process of formulating a curable thermoset resin formulation, comprising: reacting a natural cellulosic filler with at least one of: a silsesquioxane, a di-isocyanate or a polyisocyanate, a base, or an organic acid to form a reduced hydrophilicity filler, said natural cellulosic filler being selected from the group consisting of: hemp, cane, bamboo, jute, straw, silk, straw sawdust, nutshells, grain husks, grass, palm frond, coconut husk, and coconut fiber; and intermixing said reduced hydrophilicity filler with a thermoset cross linkable polymeric resin to form the curable thermoset resin formulation, wherein a molar stoichiometric ratio between isocyanate moieties of said di-isocyanate or said polyisocyanate introduced and hydroxyl moieties (—CNO:—OH) present in the natural cellulosic filler is between 0.000005-0.2:1.
