GF-01 alkyd glyptal resin


   GF-01 is a solution in volatile organic solvents of glyptal resin with oil content 46% modified with plant oils or mixed plant oils and rosin.

   It is used as a binder in production of glyptal enamels, primers, filling pastes. GF-01 –based primers are distinguished by high adhesion to substrate and other paintwork materials.
