Coating materials are widely used in construction of residential houses, office and industrial buildings, bridges, buildings, and also in the works for their repair. It uses all kinds paint materials: paints, primers, sealers, enamels, solvents. Very popular alkyd paints and varnishes, the production of which the initial components are alkyd resins and polymers obtained by polycondensation of glycerol or pentaerythritol with phthalic anhydride. Alkyd materials are divided into glyptal (a typical representative – GF-021 primer) and pentaphthalic (enamel PF-115). Pentaphthalic enamels are available in a variety of colors and can be used for painting as wood and metal products and structures. In order to extend the life of alkyd paint enamel is applied to the primed surface.
Often in the construction of the painting works to the shortening of the painting works are used nitroemali (enamel NTs-132) with the ability to dry for several hours. Nitroemali best applied with a pneumatic atomizer as well as applying the enamel with a brush is difficult because of the rapid film formation. Nitrocellulose paints also applied to prepared and primed surface. As a rule, nitroemali available ready to use, but if necessary to dilute the solvent 646. Solvent 646 is better to use, made in accordance with formulations according to GOST. Otherwise, you can use the paint material.
Surfaces prepared for painting, cover the primer GF-021 or equivalent. The use of enamel NTs-132 works in painting nezagruntovannyh surfaces is not allowed. The facades of buildings and structures are painted with acrylic paints, and with high ecological characteristics, as well as organosilicon materials, which provide weatherproof coverage. Such organosilicate compositions, such as OC-12-03, applied for painting surfaces, concrete structures and masonry structures. It should be borne in mind that the paint on the base organosilicate compositions in addition to decorative and has fire properties, since the coating nonflammable.
