Description:
Urethane hardeners of paints and varnishes
Hardener IZUR-021 is recommended for use as a second component of dark color primers and euto-enamels, as well as lacquer coatings used indoors.
Hardener IZUR-022 is recommended as the second component of varnishes and car enamels of any color, preferably light, due to the increased light resistance of the resulting coatings.
