A silane-curing chemical resistant coating composition and methods for making and using the composition are provided. A coating can be manufactured, for example, by two simultaneous or sequential processes. In the first process an inorganic material such as silica or alumina with free amine or hydroxyl sites reacts with an organic moiety having a terminating functional group, such as an oxirane, amine or hydroxyl. In the second process, the material further reacts with an isocyanato, amino or other functional alkoxy, methoxy, acyloxy or other silane group. The terminal functional becomes an alkoxy, methoxy, alcyloxy or other silane that can cross-link with another such silane group on contact with moisture and/or upon absorption of ultraviolet light. Optionally, silane terminated polymers may be further added to contribute flexibility, hardness and other desirable physical properties. The coatings are applicable to various applications including environmentally benign, high performance industrial, military and automotive applications.
