Gum Dammar is one of
the few tree resins still readily approved for use in picture varnish and
retouch varnish and as an ingredient in painting mediums, emulsions, and
encaustic colors. It is made up of alpha- and beta-resene
fractions of Damarolic acid with terpenic essential oils. Gum Dammar is readily soluble in
white spirit, turpentine, and other hydro-carbons of the aromatic variety.
This resin gives very pale films with high gloss, impermeability, and
chemical resistance, largely due to its very low acid value. It offers
excellent color stability.
