Zirconium
While zirconium driers have long been in use, this metal has come to the forefront with legislation restricting the use of lead driers in many countries. Zirconium, like lead and rare earths, serves as a through drier; and, is generally used in combination with cobalt, manganese and/or calcium. Three-quarters of a pound of zirconium will usually replace one pound of lead (based on metal). However, when substituting zirconium for lead, maximum drier performance can best be determined by experimentation. Unlike lead, zirconium is a poor pigment wetting and dispersing agent; therefore, the use of calcium or our SPURSO® may be called for when using zirconium vs. lead.
