14. A process for coating a surface with a protective polymeric structure, comprising:
-
contacting organic fiber, a solid component, and at least a first reaction component selected from the group consisting of polyol, polyamine, diamine, and mixtures thereof;
agitating the organic fiber, the solid component, and the first reaction component to transform the organic fiber into a micropulp having a volume average length of from 0.01 to 200 micrometers that is dispersed in the first reaction component;
removing the solid component to form a first reaction mixture;
contacting the first reaction mixture with a second reaction component selected from the group consisting of polyisocyanate, di-isocyanate, and reaction products of diisocyanates having isocyanate functionality, mixing the first reaction mixture with the second reaction component to form a liquid polymer selected from the group consisting of polyurethane, polyurea, and mixtures thereof wherein the micropulp is dispersed in the liquid polymer;
spraying the liquid polymer through a nozzle onto the surface without plugging the nozzle, and drying the liquid polymer to form a flexible solid protective polymeric structure on the surface. - View Dependent Claims (15, 16, 17)
