The ability of individual latex particles to spread and adhere to inorganic and organic surfaces plays a role in binding capacity of styrene-butadiene binders. Materials parameters such as elastic modulus, the work of adhesion and the thermal flow of the latex may also influence coating strength. Latex emulsions are often characterized by bulk properties such as mean particle size, glass transition temperature and gel content. A relationship between these bulk characteristics, the ultimate coating strength and the micro scale behavior has not yet been established.
