Abstract: Provided is a coating composition comprising (a) a component A of the formula (R1)dSi(OR2)4−d, wherein R1 is a C1-C3 monovalent hydrocarbon, R2 is an R1 or a hydrogen radical and d is 0, 1 or 2; (b) a component B selected from the group consisting of (R3)aSi(OR4)4−a (Formula 1) and/or (R5O)m(R6)nSi(R9)x(R10)y Si(R11)zSi(R)o(OR7)p (Formula 2); (c) metal oxide particles; (d) UV absorber; (e) a catalyst; and (f) a solvent. The coating composition may provide a coating exhibiting good optical properties as well as durability, abrasion resistance, and/or crack resistance.
