A coating composition having improved abrasion resistance is provided, which comprises (A) a composition comprising (1) an organooxy-chainstopped organopolysilsesquioxane, (2) a tetraorganotitanate, (3) (a) a siloxane-functionalized ester having the general formula (R.sup.3 O).sub.3-2n SiO.sub.n R.sup.4 OC(O)R.sup.5 C(O)OR.sup.6, wherein n is equal to 0, 1/2, or 1, each R.sup.3 is independently a saturated or unsaturated monovalent hydrocarbon radical containing from 1 to about 20 carbon atoms, R.sup.4 is a divalent hydrocarbon radical containing from 1 to about 20 carbon atoms, R.sup.5 is a divalent conjugated olefinic radical having from 2 to 4 carbon atoms, and R.sup.6 is R.sup.3 or R.sup.4 SiO.sub.n (OR.sup.3).sub.3-2n ; or (b) a cyanoorganotriorganooxysilane: and (4) an organic carboxylic acid ester; and (B) from 0% to about 85% of a volatile diluent. Also provided is a coating composition having improved abrasion resistance wherein part (A) is a copolymer of the organopolysilsesquioxane (A)(1) above and the ester (A)(3).

Abrasion resistant coatings for glass articles

An improved coating composition suitable for concealing scuff marks on glass articles is provided, comprising by weight (A) from about 70 to about 100 percent of a composition comprising by weight (1) from about 50 to 75 percent of an organooxy-chainstopped organopolysilsequioxane having a viscosity of from about 5 to about 1000 centipoise at 25.degree. C., (2) from about 5 to about 15 percent of tetraorganotitanate, (3) from about 0 to about 25 percent of an organotriorganooxysilane, and (4) from about 0 to about 15 percent of a carboxylic acid ester, and (B) from about 0 to about 30 percent of a volatile diluent. The coating formed from this composition has improved cure rate and masks wet bottles uniformly and completely.
