    Water-dispersion paints

    Water-dispersion paints Water-dispersion (water-based) paint are used primarily for painting walls and ceilings, is very easy to use, do not contain organic solvents, due to which almost no odor and are considered environmentally friendly. Applied by brush, roller or spray and to form a coating having a high degree of adhesion (adhesion) with the majority of bases that allows repainted surface without any pretreatment. The particles of the binder in waterborne paints are dispersed (dissolved) in the water, and, after its evaporation, stick to each other, forming a film, providing paint   good performance. However, water-dispersion paint lose their properties during freezing, so cold weather have to be stored in a heated room.            

    Water-dispersion paints are made, in most cases, the white, which makes it possible to achieve any color (including simulation   gold, silver, platinum, etc.) by adding a special toning dyes (callers) . Tinted paint may immediately before use, so to speak, by hand, but this is difficult to achieve the desired shade and the more difficult in this case necessary to repeat it. Therefore, if you plan a lot of work, it is best to use a special tinting machine, which allows not only to obtain any necessary amount of paint of the desired color, but the color and repeat if necessary. To select the desired color in all the world's leading manufacturers of paints have their tinting map where each hue is assigned a number.        

    The properties of waterborne coatings and their value depends on what kind of polymers used as the binder. The most inexpensive - paints based on polyvinyl acetate dispersion (PVA), has good lightfastness, but   low water resistance and therefore often used for painting walls and ceilings in dry conditions. Adding acrylic polymers in the paint on the PVA binder to some extent, increases water resistance and abrasion resistance of the finished coating, but these colors still inferior created on the basis of pure acrylic binders, although their value is almost the same.

    The types of water-dispersion paints:
    Butadiene-styrene   dispersion have good water resistance, but have limited light fastness, resulting in the appearance of prominent yellow. Paints   this type are inexpensive and can only be used indoors with artificial lighting dim.

    Acrylic dispersion is, perhaps, most of all waterborne paints and, in spite of the higher cost, most often used for interior decoration. They have a universal character and high performance, can achieve almost any color (stated by more than 15 thousand.) And still retain excellent color even under intense UV irradiation.  

    In general, water-dispersible   easy to apply paints, dry quickly to form an elastic, water-repellent surface, they can be painted wet surface (for better adhesion recommend still applied to the dry surface), they are not combustible and, finally,   pass water vapor (which is called « breathe »), increasing the comfort of living quarters. However, due to lack of mechanical stability, they are not suitable for staining the floor.
