Aqueous polymer dispersions

摘要

An aqueous polymer dispersion containing polymer particles formed of at least two polymers, the polymer particles of the dispersion having a minimum film-forming temperature below 60 DEG C and being formed of two different polymers namely polymer A having a glass transition temperature (TgA) of not more than 10 DEG C, and forming from 5 to 65% by weight of the total polymer ; and polymer B having a glass transition temperature (TgB) of more than 25 DEG C, and forming from 5 to 65% by weight of the total polymer together with a multifunctional material (C) present in an amount of from 5 to 70% by weight of the total polymer system.
