Abstract

The influence of solvents in the composition of the paintwork material on the properties of coatings was studied. For research, paints and varnishes based on polyurethane film-forming agents cured with an isocyanate hardener were selected. Solvent R-189 from various manufacturers was used to dilute paints and varnishes. Using the method of gas chromatography-mass spectrometry, the qualitative and quantitative composition of the used solventsR-189 was determined. It has been established that the studied solvents from various manufacturers do not comply with TU 6-10-1725–78, and a significant effect of the composition of the R-189 solvent on the properties of the obtained coatings has also been shown.
