The article presents the properties of the cyclohhexane resins with particular attention paid to polycyclohexane produced under the brand name of Laropal К 80. In connection with the universal application of this resin for the production of painting varnish ( for final and retouching purposes ), the ways of increasing their flexibility have been discussed as well as their resistance to the processes of thermo-- and photo-oxidation which result in yellowing, increased fragility, and loss of solubility in liquids of little polarity ( for example, in purified gasoline ). The article stresses the optical merits of the cyclohexane varnishes, similar to those which are possessed by dammar and mastic varnishes in relation to the layer of oil point.
