Silicone coating agent composition and article

Abstract

Provided is a condensation-reaction-curable silicone coating agent composition which contains, as a main component, a hydrolysable-group-containing organosiloxane mixture and also contains a curing catalyst, in which the hydrolysable-group-containing organosiloxane mixture contains an organotrisiloxane compound having a specified molecular structure in which there is at least one non-substituted, halogen-substituted or alkyl-substituted phenyl group in the molecule thereof and at least four hydrolysable groups are contained at molecule chain both ends thereof and an organodisiloxane compound having a specified structure in which there are at least two non-substituted, halogen-substituted or alkyl-substituted phenyl groups on one silicon atom in the molecule thereof and at least two hydrolysable groups are contained on the other silicon atom in the molecule thereof, and the organotrisiloxane compound and the organodisiloxane compound are contained in the hydrolysable-group-containing organosiloxane mixture at a specified blend ratio. The silicone coating agent composition has excellent storage stability although no organic solvent is contained, and can be cured rapidly at ambient temperature after being applied on a substrate to provide a cured coating film having excellent transparency, adhesiveness and the like, having excellent conformability to the shape of the substrate upon the bending of the substrate, and capable of preventing the corrosion of the substrate.
