Block resistance is one of the many performance requirements demanded of paint consumers today. This article discusses the role of latex in delivering on this goal. By utilizing a variety of polymer optimizations, removal of fluorosurfactant additives from formulations is possible without sacrificing other key properties.
This article describes a new higher-block-resistance VAE under development that significantly minimizes the trade off between block resistance and scrub resistance in VAE-only paints. Additionally, this new VAE continues to maintain high scrub resistance even in low-sheen paints, enabling the formulator to use a single-VAE binder across all sheens.
