Calcium driers are clear colourless medium viscosity solutions of calcium metallic salt with 2- ethyl hexanoic acid in mineral spirits or esters.
Calcium carboxylates are auxiliary driers that promote the activity of other driers and especially of through –
driers such as lead and zirconium. Therefore, they show poor drying action on their own.
It is possible to replace a part of lead with a large amount of calcium to prevent the precipitation of lead and maintain the drying efficiency.
Neutral calcium driers also promote pigment wet and dispersion, improve hardness and gloss, while reduce skinning.
Finally calcium is preferentially adsorbed by drier adsorbing pigments and consequently minimises the dry activity loss of the system.
Calcium is the least toxic metal and it is used in paints where lead should be avoided.
Applications
Calcium drier is normally used in combination with other driers such as Cobalt, Lead, Manganese and Zinc.
It is successfully used to lead free drying mixtures and improves the drying rate of Cobalt and Strontium.
