Amino alcohols, such as 2-amino-2-methyl-1-propanol (AMP™), are commonly used as stabilizing agents in a wide range of waterborne coating formulations. Through their multitude of interactions with different coating ingredients, amino alcohols enhance storage stability, provide pH control, and enable better dispersions of pigments. In particular, the strong interaction of amino alcohols with pigment surfaces makes them powerful co-dispersants to control pigment particle size and stability, which critically affects optical, mechanical, and rheological properties. Industrial waterborne coatings face challenging performance criteria, and amino alcohols are an effective formulating tool to help meet those challenges. We show in a waterborne direct-to-metal (DTM) coating formulation how the co-dispersancy properties of AMP can be utilized to improve hiding, gloss, and corrosion resistance. Amino alcohols can also be used to reduce the number and level of other coating ingredients, further enabling formulators to optimize the performance of DTM protective coatings.
