Novel oil-modified acrylic multi-domain dispersions

Water-borne acrylic dispersions and alkyd emulsions have been extensively used for architectural coatings for decades, each technology having its advantages and drawbacks. While alkyd emulsions generally exhibit very good application characteristics such as high gloss and good penetration, they lack in performance for weathering resistance. Acrylic dispersions, conversely, are disadvantaged in terms of flow, leveling and appearance, but perform well for outdoor durability. Many attempts have been undertaken to find the balance of performance by hybrid technology approaches. The presented work highlights a novel synthetic approach to oil modified acrylic multi domain dispersions combining acrylic-like outdoor durability with alkyd-like appearance and application behavior. This innovative synthetic concept, along with supportive performance testing results, will be outlined and discussed.
