Alkyd Artists Paints (Art & Chemistry)
Alkyd resin is
synthesized from plant and vegetable oils, like linseed or soya oil,
that is modified (oil-modified alkyd resin) for use in artist’s oil
paints, mediums and grounds. I convert linseed oil (tung oil, crambe
oil, walnut oil, etc with some castor oil additive) , for example, into the
mono-glyceride derivative with glycerol, followed by reaction with
phthalic anhydride.When it is dry alkyd is tough, flexible and resistant
to solvents. The main advantage of alkyd is in the speed at which alkyd
resin dries. Alkyd oil paints or oil paints with added alkyd mediums
will usually be touch-dry in 24 hours, if painted in a normal thin film.
They become tacky within a few hours so brushstrokes can be added
without disturbing the earlier paint.
