A study of three commercial semigloss paints examines how silane-modified colloidal silica, drying time and rheology modifiers influence block resistance.
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.
