Water-based coatings use water as the primary carrier (vs organic solvents in conventional coatings). Main binder types: acrylic emulsions (good UV, flexibility), polyurethane dispersions (excellent abrasion, chemical), epoxy emulsions (high crosslink, corrosion), and hybrids (balanced properties). Understanding the chemistry helps select the right product for each application.
Introduction
Water-based coatings use water as the primary carrier (vs organic solvents in conventional coatings).
