Lead drier

Description

Organic salts of lead used to speed the curing time of oil drying oils. Lead driers act as a polymerization catalyst, curing the film evenly. It is sometimes mixed with drier cobalt driers to aid in hardening the lower portions of an oil film. Examples of lead driers are: acetate lead acetate, linoleate lead linoleate, oleate lead oleate, and naphthenate lead naphthenate. Some lead pigments also act as driers, such as oxide lead oxide and carbonate, basic basic lead carbonate. Because of laws banning the use of lead additives, lead driers are no longer commonly used. Replacement driers include salts of calcium and zirconium.
