Water-dispersion paint: the types and properties

Water-dispersion paints are considered one of the most convenient and cost-effective building materials.Due to the fact that they contain no organic solvents, they have almost no smell.Water-dispersion paints are completely safe from an environmental point of view.They have excellent adhesion to a wide variety of different types of surfaces.Apply can be spray, roller or paint brush.They have excellent performance.Thanks to these properties, the dye dispersion occupies a leading position among the materials used for coating the surface.

of the particles in the material dispersed throughout its volume, after the evaporation of the moisture they approach.They adhere to each other upon contact, forming a film.The water-dispersion paints usually produce white.To get the color you want, or almost any shade of Kohler applying toning dyes.Tinting can be done either manually or with special machines.The main disadvantage of the first method is the difficulty of compliance identical proportions to obtain the sa

me colors under the following mixing.That is why all manufacturers use tinting machines and card (number color, proportion).

Water-dispersion paints are divided into several types depending on the binder.The cheapest and restrictions apply - materials on the basis of PVA (polyvinyl acetate).They are mainly used for painting walls and ceilings in rooms with low humidity.In the case of adding them acrylic polymers can improve abrasion resistance and water resistance of the coating future.Styrene-butadiene binder materials have excellent resistance to moisture, but can not tolerate exposure to UV light and turn yellow in the sun.For this reason, they are used inside buildings in rooms with artificial lighting.

Water-dispersed acrylic (where as binding - only the polymer) is the most versatile.Most of the materials produced today fall into this category, they are most often used for painting works.

Paints on this basis is excellent tintable.However, their use must be taken in the selection of shade material from the same manufacturer, as he may not match due to differences in the systems of the tinting.Acrylic-based paints dry quickly.They are well tolerated exposure to sunlight.These materials allow a rubbery coating to close fine cracks, well tolerated and are washing long enough.There are variations, specially adapted for painting "live" wood.Such paints increased flexibility and good water vapor permeability combined with a water-repellent properties.

Regardless of the type of binder from these paints have one weak spot: they become useless in the event of freezing, so during storage should be provided a positive temperature.
