Strontium drier is a clear solution with medium viscosity of strontium metallic soap of a synthetic fatty acid in mineral spirit
Properties
Strontium as drier is not widely used yet. This metal is another alternative for lead legislation restriction.
Strontium seems to overcome the insufficient Zirconium performance and is about to be the most prominent choice for lead substitution.
Strontium promotes through drying and unlike Zirconium does not cause yellowing.
In addition it is a good pigment - wetting and dispersing agent preventing haze and wrinkling.
The toxicity of strontium driers is comparable to calcium while its maximum drier performance can best be determined experimentally.
The addition of accelerators increases its efficiency even further.
Application
In lead free paints.
In combination with driers such as: Cobalt, calcium and manganese.
To high solids systems.
