The basis for the production of coatings (paints) in our country are the Alkyd binders, despite the rapid development of production and consumption of clean water-based paints. Alkyd materials up, including oil paint, at least 65% of the total consumption of paints. All market participants paint recognized that coatings based on oil-based paints MA-15 MA-25, gustotertyh paint on the basic parameters on the basis of inferior coatings Alkyd Low price of oil paints – their main advantage, but it makes no sense, since consumption of these materials per 1 m 2 surface is significantly higher than when using alkyd enamels. Duration of drying oil paints is much greater than that of alkyd enamel. This extends the date of the painting work. Most widely used in construction during the finishing and repair work is used enamel PF-115 (GOST 6465-76). It is produced as large paint factories, and small manufacturers that are dispersing equipment. Enamel PF-115 is produced semi-finished varnishes on the basis of the FS-060 or FS-053, a modified rosin.
Formulation of enamel in 45 years its existence, has undergone many changes, which were intended to reduce costs by reducing consumption of expensive components (edible oils, titanium dioxide). However, all these changes in the formulation did not lead to improved quality of coatings. Visit MasterClass Founder for more clarity on the issue. It should be recognized so that the enamel PF-115, issued today by most manufacturers do not fully meet the requirements of local quality standards and increased consumer demands. Nevertheless enamel PF-115 is the most common in the range of virtually all paint factories. Depending on the recipe, ie, the quality and, consequently, raw material costs, there is great variation in prices from manufacturers. It should be noted that the price of the FS-115, manufactured by large paint factory – Zagorski, Yaroslavsky and others, significantly higher than in small firms also produce enamel PF-115. This is explained by only use of (small producers) in the formulation of low-quality semi-finished paint and use cheap fillers such as chalk, instead of costly titanium dioxide. Therefore, users should use the products of proven large paint factories. The desire to save money by buying a cheap little-known manufacturer of enamel is wrapped in real losses due to increased consumption of enamel deposition and low-quality coverage.
