FIELD: varnish-and-paint industry.
SUBSTANCE: invention relates to polyurethane coatings intended to be applied on a variety of surfaces (metal, wood, etc.). Composition comprises toluene solution of hydroxyl-containing component and toluene solution of polyisocyanate. Hydroxyl-containing component is oligoether obtained by in-melt reaction of tall oil with triethanolamine at 170-200°C and characterized by viscosity at most 10000 mPa·s, acid number at most 5.0 mg KOH/g and hydroxyl number 125-138 mg KOH/g. Oligoether-to-polyisocyanate ratio is 1:1.
EFFECT: enabled preparation of two-component lacquer with elevated light resistance, water resistance, and stability, which is suitable for anticorrosive coatings on metal products.
