Abstract
Modified chrysotile fiber can be used as a filler in the epoxy-polyester powder composition to improve its physicochemical properties and obtain a thermosettable polymer coating with improved properties.
Purpose: The aim of this work is to study the chemical composition of the initial and fiber-modified chrysotile powder composition and evaluate physicochemical properties of polymer coatings.
Research findings: It is shown that the chemical composition of the initial powder composition changes after the addition of modified chrysotile fiber. The salt and acid resistance of the obtained polymer coatings increases. The porosity of coatings filled with fibers decreases in comparison with unfilled ones. The heat resistance of the obtained polymer coating with the addition of modified fibrous fillers grows at heating at 190 and 550 °C.
