Abstract
The major paint companies viz. Berger and Asian paints has switched over to lead free paints to meet the demand from industrial sector. Many certification bodies came forward to certify these lead free paint products so that these products can be marketed internationally. Also paint manufacturers view is that the organic pigments based colours should match the quality of shades as that of inorganic lead chromate based pigments but for colour yellow/orange and red there is no good hiding effect but not for other colours. Yellow/orange and red lead chrome based compounds are in greater demand because of good hiding effect and bright shade. Some of the paint manufacturers are using iron oxide and/or alloxides but it gives a buffy colour. Also one can use cobalt and manganese in place of lead for good hiding effect. For quick drying purposes lead can be replaced by zirconium and calcium based compounds. Most of our decorative paints do not have lead contents except few enamel paints with selective shades yellow and orange and lead content is minimal.
