1. A silicone coating composition comprising:
(A) 100 parts by weight of a hydrolyzable group-containing organosiloxane mixture consisting of (A-1) from 20 to 95 parts by weight of a hydrolyzable group-containing organotrisiloxane compound of general formula (1-1) below and (A-2) from 80 to 5 parts by weight of a hydrolyzable group-containing organodisiloxane compound of general formula (1-2) below

OG Complex Work Unit Chemistry
wherein R1 and R4 are each independently an unsubstituted or halogen-substituted monovalent hydrocarbon group of 1 to 10 carbon atoms, R2 is an unsubstituted, halogen-substituted or alkyl-substituted phenyl group, R3 is an unsubstituted, halogen-substituted, or alkyl-substituted monovalent hydrocarbon group of 1 to 10 carbon atoms, each X is independently at least one type of hydrolyzable group selected from the group consisting of unsubstituted or alkoxy-substituted alkoxy, aryloxy, alkenyloxy, acyloxy and ketoxime groups, and ‘a’ is independently 0 or 1 for each bonding silicon atom,
with the proviso that the combined amount of component (A-1) and component (A-2) is 100 parts by weight; and
(B) from 0.01 to 10 parts by weight of a curing catalyst.
