/ Natural Resins / RESINS Damar
Damar is a natural resin used primarily in ink, paint, polish, varnish and finishing compositions. Damar provides a unique depth of gloss, superior color and gloss retention, adhesion and flexibility. Damar also provides resistance to fumes, scuffing and grease.
Damar is a general varnish resin for cold-cuts, blends and cooked oil vehicles. Due to its fume resistance and binding value, Damar is recommended for use in white enamel and pastels.
Damar is not completely compatible with lacquer solvent and must be treated with a process known as dewaxing for use in nitrocellulose lacquer. Damar is dissolved in a solvent and the resin wax is precipitated by ethyl alcohol. Dewaxed damar is tough and versatile as a lacquer resin. It is used as a spirit varnish over artistic paintings to shield against dirt. It is FDA-approved for use as a coating for food containers.
