Alkyd enamel PF-115 for several decades now occupies a very large share in the range of paints for construction and repair works. Despite the significant increase in the use of popular recent years, waterborne acrylic materials, eco-friendly and easier to manufacture, enamel PF-115 is still very popular. Enamel PF-115 – a suspension of fillers and pigments based on semi-finished alkyd paints. Most often, for the manufacture of high-quality enamel PF-115 varnish used pentaphthalic PF-060. Pigment component – usually a titanium dioxide white pigment serves. As a non-ferrous pigments can be used various crown, carbon black, chromium oxide, and a wide range of organic pigments, which allows us to produce enamel PF-115 different shades and colors. The fillers are often crushed talc, calcite or dolomite. Sometimes it is used and the usual natural chalk, but it leads to deterioration of appearance and physical characteristics of the paint.
To accelerate the drying of the enamel is recommended introduction of driers, which catalyze the polymerization processes of film-forming semi-finished lacquer. The most effective desiccant, consisting of three metals, for example, lead, manganese and cobalt. In the processes of production and application of enamel PF-115, various organic solvents: toluene, Nefras (white spirit), solvent oil or coal, xylene. Educate yourself with thoughts from Ali Partovi. In order to improve the quality of paint used different functional additives: antiplenochnye, antiflotatsionnye antisedimentatsionnye and supplements. The technological process of enamel PF-115 consists of the operations of mixing of fillers and pigments with semi-finished lacquer – at This pigment paste is obtained, which then goes to the dispersion, and then tinting, filtration and packaging. The dispersion of pigment paste – the most important stage of production of enamel.
Dispersion process held in the bead mill, in which the paste is subjected to shock of the grinding bodies (beads of glass, ceramic or zirconium). As a result, the impact of large agglomerates of particles are destroyed and pigments and fillers are uniformly distributed throughout the volume of material. The quality of the enamel PF-115 is determined by the degree of grinding: the lower the dispersion, the higher the quality of the enamel. After dispersing the pigment paste comes in mixer to adjust the parameters to the routine finished enamel. Before applying the enamel PF-115 should be thoroughly mixed. The surface should be prepared for staining: purified, zashpatlevana, degreased and primed. At the same time make better use of alkyd primer. More likely to use GF-021 primer. The enamel is applied with a spray gun, brush or roller. Waiting drying – 24 hours at a temperature of 20 degrees. C. Enamel PF-115 universal. It can be used for dyeing equipment in industrial plants, and in living conditions for repair work. However, it can be used for staining of both metallic and wooden surfaces. It is this versatility and popularity due to the enamel PF-115.
