LEAD

LEAD

• Lead is the most important auxiliary thorough drier. It is used with active driers like Cobalt and it promotes thorough drying by virtue of its polymerizing effect. Lead promotes hard thorough drying throughout the entire film, with out effecting flexibility. Along with Lead, use of a small amount of Calcium and an active drier like Cobalt will be desirable. For internal & moderate external temp, these auxiliary driers work well with common active driers. Lead may not be used in aluminum paint where it interferes with leafing and has to be avoided in fume resistant paints as well. Govt. legislation now limits the lead content in residential paints to 0.86%. Lead is available as stable solution in MTO in various concentrations.
