摘要:
A method of making a titanium oxide-containing coating composition comprises attaching an initiator to a pretreated titanium oxide to form an initiator/pretreated titanium oxide complex. The pretreated titanium oxide includes a plurality of pretreated titanium oxide particles which are titanium oxide particles that are pretreated with at least one metal oxide. The initiator/pretreated titanium oxide complex is contacted with a polymerizable unsaturated monomer such that a polymeric encapsulate forms on the initiator/pretreated titanium oxide particles to form polymeric encapsulated titanium oxide particles.
摘要:
Methods for enhancing the deicing properties of a cementitious substrate using a polymer-based coating are provided. Coating formulations and coated cementitious surfaces are also provided. The methods comprise applying an aqueous emulsion to a surface of the cementitious substrate and allowing the aqueous emulsion to dry, such that a continuous, fluorine-containing, polymeric coating is formed over the surface of the cementitious substrate. When applied to a cementitious surface, the coating penetrates into the underlying cementitious substrate and bonds with the substrate to provide the cementitious surface with hydrophobic and other properties that improve the deicing properties of the surface.
