Cobalt Driers Accelerates the drying time for oil colours and mediums. Surface drier. Contains cobalt salts, which act as catalysts to speed up the oxidation and polymerisation processes in drying oils, such as linseed. Add cobalt driers in small quantities to oil paints or mediums. Excessive dosage may lead to issues such as brittleness or…
Zirconium Driers Accelerates the drying time for oil colours and mediums. ‘Through-film’ drier. Zirconium siccative in mineral spirits. Zirconium driers do not react on their own but in combination with other reactive siccatives such as Cobalt Driers. Used to equalise stresses in drying rates within thick paint films to prevent surface wrinkling. Use sparingly as its…
