Improved polymer technology has enabled the volatile content of house paints to be dramatically reduced to very low levels over the years. Life cycle assessment has shown that another opportunity for improving the eco-profile of architectural coatings would be to reduce the level of TiO2 (opacifier) required. TiO2 is typical used inefficiently due to a phenomenon known as “crowding”. Adsorbing latex technology which enables the controlled formation of self assembled polymer-pigment composites has been developed. This is a smarter material which replaces the conventional paint binder and does everything the conventional binder does while additionally helping to improve pigment efficiency. Better film formation and reduced impact of photodegradation can result from this more uniform distribution of TiO2, all while improving its efficiency and improving the eco-profile. Production of this technology is measured by millions of pounds and was awarded a Presidential Green Chemistry Challenge Award by the Environmental Protection Agency.
