Water Reducible Coatings: Hybrids Come in Many Forms...




Water Reducible Coatings are film-forming agents that usually contain a oil modified or epoxy-borne resin structure that is pH modified, or neutralized, to increase the ability of the resin's solubility into water via an emulsification process. These resins are blended with alcohols, glycol's, and intermediate surfactants to allow the absorption of water into the oil phase of the resin, creating a homogeneous solution of oil and water.

Commercial architectural painters and industrial flooring specialists will recognize this technology in the form of 2-part epoxy coatings used for concrete, masonry and structure steel coatings. Modern applications vary, ranging from chemical and fuel resistant coatings applied to aircraft hanger floors to specialized paints used to protect the hulls of supertankers and modern Navies. Likewise, the modern woodworker and cabinetmaker will recognize the term, “hybrid varnish” when shopping for alternative wood finishes to replace their dangerous, solvent based lacquers…
