Abstract: A coating composition is shown and described herein. The coating composition comprises: the (meth)acrylic polymer containing at least one active hydrogen (a), the epoxy silane oligomer composition (b), emulsifier (c), titanium oxide particles (d), a siliceous particulate filler (e) and water (f) optionally one or more additives, where the epoxy silane oligomer composition comprises 5 to 15 weight percent monomer, 5 to 20 weight percent dimer, 5 to 20 weight percent trimer and 45-85 weight percent poly-oligomers components. The coating composition can provide a water-based coating composition exhibiting early water resistance such that defects in the coating are minimized if exposed to water prior to the coating being fully cured.
