Over the years the optimization of water‐borne emulsion polymers has resulted in water‐borne coatings with excellent exterior durability and significantly reduced solvent emissions versus solvent‐borne coatings. In recent years, pressure to further reduce emissions has necessitated the use of softer polymer compositions which can negatively impact gloss and tint retention, and dirt pick up resistance. The use of heterogeneous polymer morphologies are addressing these short comings; however care must still be taken not to affect paint durability. The development of low solvent emission thickeners and mildewcides has allowed further reduction in paint emissions.
