    Abstract: The present disclosure relates to water-based coating compositions useful for forming protective coatings on substrates. The water-based coating compositions comprise an aqueous carrier, a binder component comprising at least one chlorinated resin, a filler component comprising at least one carbonate type filler, and at least one anti-corrosion agent, wherein (A) the binder component further comprises at least one epoxy-functional resin in an amount corresponding to a weight ratio of the at least one epoxy-functional resin to the at least one chlorinated resin of at least 0.1, and the composition has a filler to binder ratio on a weight basis of 1.0 or more, or (B) the composition has a filler to binder ratio on a weight basis of 2.0 or more. The present disclosure also relates to coatings, coating methods, coated articles and uses, derivable or making use of the water-based coating compositions. The resulting coatings may exhibit enhanced properties including for instance excellent thermal stability, heat resistance, durability and/or good barrier and corrosion protection properties.
