Zirconium is a most useful &
efficient auxiliary drier. Zirconium like lead
serves as a through drier & is generally used in
combination with Cobalt, Manganese & Calcium. Unlike
Lead, Zirconium is a poor pigment wetting &
dispersing agent.
Zirconium is an active cross-linking
agent & as such improves hardness of stoved films as
well as their adhesions.
Zirconium is not as effective in
Phenolic resin based media it is recommended as a
catalyst for epscy esters. Use of Lead driers in
combination with Zirconium is to be avoided totally.
