Performance Characteristics of Coatings Created with Alkyd and Oil- Based Materials in Wooden House Construction

Abstract

The paper deals with the issues and study of the properties of varnish-and-paint materials which are used to create protective-anddecorative coatings for joinery and building structures. The article provides an examination of comparative studies on the qualitative characteristics of alkyd varnish (PF-283) and drying linseed. Changes in the drying time of linseed oil and alkyd (pentaphthalic) varnish are determined depending on the material consumption and drying temperature. The studies have shown that the drying rate of films at the same material consumption at temperatures of 50 and 80°С is practically the same and ranges from 80 to 114 minutes. The article also presents the results of studies on the performance properties of finishing materials (coating thickness, water and heat resistance). It was found that alkyd varnish-and-paint materials form a coating of greater film thickness and hardness. In terms of water-resistance and heat-resistance, coatings based on drying oils have higher performance indicators. Recommendations are given for the use of alkyd and oil-based varnish-and-paint materials for finishing joinery and building structures made of oak wood which are used in wooden house construction.
