Abstract
A coating composition suitable for providing a thermoformable hardcoat is disclosed. The composition contains a silane-containing oligomer (A), a silane (B) having the general formula R3cSiX(4-d) wherein each occurrence of R3 is independently a C1-C8 alkyl, C2-C8 alkenyl or C6-C20 aryl, each occurrence of X is a halogen atom, C1-C6 alkoxy, C1-C6 acyloxy, C1-C6 alkenoxy or hydroxide; d is 0, 1 or 2, a metal oxide (C) and a condensation catalyst (D) wherein components (A), (B) and (C) are hydrolytically condensed in the presence of component (D) to achieve a T3 to T2 ratio of from about 0.3 to about 2.5.
