Zirconium is the second most efficient cross-linking agent, which generally replaces the lead in more environmentally acceptable systems. Although it exhibits better gloss and colour retention compared to lead, zirconium driers do not perform as well as lead under adverse drying conditions such as low temperature and high humidity. Zirconium, as a strong cross-linking agent, contributes hardness and provides better adhesion. Additionally, it is widely used in white paint since it reduces the yellowing tendency when used in combination with cobalt and calcium.
