<p>A neutralised organic polymer for use in a film forming composition in which the emulsion contains a fixed base, at least 5 % of which is a lithium base is provided. Also provided is a neutralised coating composition containing a fixed base, in which the fixed base comprises at least 5 % weight/weight lithium base, with the proviso that the neutralised coating composition does not include a zinc silicate paint composition. Preferably the lithium base is lithium hydroxide which helps to avoid the impairment of water resistance, improve application properties of paint compositions, improve stability and effectiveness of oxidative cure such as promoted through metal drier catalysts and achieve a lower degree of film yellowing than paint compositions comprising conventional fixed base or amine components.</p> |
