Base oil paints

img20Base oil paints “11″ “(for priming). They are a suspension of white and colored dyes and weights in diluted flaxseed. They give a semi-matte to matte shine. Suitable for brush work. Level of flow - the permissible visibility of brush marks. Drying at 18-22 ° C with average air humidity; the painting should be dust-dry after 12 hours., a po 24 at. completely dry. The sediment that forms at the bottom of the paint vessel should be able to disperse over the period 4 months from the date of manufacture. Colors encountered: white, blue, ultramarine, light green, khaki, nuts: bright, average, dark, mahogany, brown, light gray and black. Primer oil paints are used first, the bottom layer on varnished wood or directly on iron, when the object is not exposed to the weather or moisture. Highly protective miniature lead paint. It is a dry red lead suspension with the possible addition of other solid dyes or weights (e.g.. heavy spar) in a good quality, thinned linen form. It has the color of dry red lead (orange-red). It is used for direct priming of rust-free and degreased iron as the first layer (priming). Lead mini paint, properly crafted, shows excellent protective properties. In order to maintain its essential value as a primer, it should be covered with a surface layer after 2–5 days. Coating at a later date (e.g.. a couple of weeks) it is pointless, because during this time the paint may have already been exposed to the damaging effects of mechanical factors, lights, humidity and temperature. The maximum period of use of the paint from the date of production - 6 do 8 weeks. Do not accumulate large amounts of mini-paint in material bases and on construction sites. Due to the serious shortage of red lead, efforts are constantly made to replace the mini oil paint with materials with similar properties.. A material suitable for a partial replacement of the mini paint is phosphoric alcohol rust remover. The main application of this material is for derusting steel surfaces, eliminating more expensive, more difficult and not always effective mechanical derusting. Phosphor rust remover is produced on the basis of phosphoric acid with the addition of small amounts of zinc oxide and manganese. The rust remover works by chemical action on the rust, i.e. oxides. iron and the production of iron phosphate, zinc and manganese. After lubricating the rusty surface with a rust remover, converted and dry, a good base for further protective coatings is obtained. This primer is a kind of protective coating. The produced phosphate coating is not very hard and porous, therefore it shows low resistance to abrasion and scratching. It is dark, gray to black. A white scratch on the produced coating indicates a proper reaction. If the scratch is yellow, derusting must be repeated, for it has not happened sufficiently. The produced coating is a good insulator. It is not resistant to acids and bases. It is resistant to re-rusting for a period of several days to several months, depending on the environmental conditions. Therefore, it should basically be used as a base for further protective coatings. As a material that eliminates mini-paint, phosphor rust remover can be used for steel structures under the roof and for less important objects exposed to weather conditions.. In addition, it should be used for coating a variety of steel products exposed to atmospheric corrosion, which so far have not been protected at all.
