Electrically conductive coating composition of a glycidyl acrylic polymer and a reactive polysiloxane

摘要

A coating composition having a liquid carrier and a binder of a blend of a. an acrylic polymer containing glycidyl groups and b. a crosslinkable polysiloxane having attached to the silicone atoms of its backbone alkyl groups, phenyl groups and hydroxyl groups; the composition contains electrically conductive pigments such as carbon black and graphite to provide an electrically conductive dry film; the composition is used on lead alloy grids of lead acid storage batteries to prolong the life of the battery or to reduce a size and weight of the battery.
