Is a solution of petroleum resin, produced by thermal polymerization of C9 fraction (liquid products of naphtha pyrolysis) in white-spirit or heavy petrol. It is used as a film-forming component in paints and enamels production, as well as treatment of wooden, plastered and concrete surfaces prior to painting.
