Résumé : |
Heavily-fluorinated polyurethane coatings have been formulated and tested in demanding marine applications. In addition to the chemical and weather resistance typical of polyurethane coatings, these coatings have an anti-adhesive surface which permits the facile removal of water, ice and soil. This paper describes the chemistry of the polyol resins, the formulation of these resins into tough, anti-adhesive polyurethane coatings, and performance of these coatings in rigorous marine and industrial applications. |
