Acrylic paints
– Water dispersion paints based on polyacrylate. Used in construction works indoors and outdoors. In the process of producing water-emulsion paints, scientists had to combine incompatible – water-insoluble polymers and water. The created polymer systems in water got the name – latexes (emulsions or dispersions). Hence the names of water emulsion paints, water dispersions and latex paints.
Acrylic paints, just like other water-dispersion paints, can be diluted with water and tinted with water pigment pastes, but unlike water-dispersion paints – after drying they become resistant to water.
The main advantage of acrylic paints is their high elasticity and water repellency properties in combination with high vapor permeability. Acrylic paints can be applied with a brush, roller or spray. The acrylic coating dries in 30-40 minutes and hardly smells. The acrylic paint layer has high adhesion and high performance characteristics – it is flexible, durable, washable, as well as the acrylic paint layer retains the color tone for a long time and withstands intense ultraviolet radiation.
The paints used in the interior must first be ecologically safe – housewives must come into contact with painted surfaces every day and every hour.
The most environmentally friendly paints are water-dispersion paints. The binder of such paints is diluted not with an unhealthy organic solvent but with water. It is water dispersion paint specialists recommend using it on large areas – walls, floors, ceilings, partitions, etc. Alkyd and oil paints can also be used in the interior, but in small quantities, for example, when painting window panes, metal pipes and heating radiators.
Water-dispersion paints have a number of advantages. For example, after application, they dry very quickly – an hour and a half (for comparison: oil and alkyd paints stain for at least another day). The range of uses of water-dispersion paints is very wide. They can be easily applied to pre-primed concrete, plasterboard, plaster, wood and even metal.
It should be noted that the properties and price of water-dispersion paints depend to a large extent on the polymers used. The cheapest are polyvinyl acetate-based compositions (PVA). Such paints adhere well to surfaces, practically do not fade, but are afraid of moisture. Therefore, their use is possible only in dry rooms.
On the contrary, butadiene styrene dispersions are distinguished by water resistance. However, it is less resistant to light and over time turns yellow.
Compositions based on acrylic dispersion are considered to be the assortment of gold middle water dispersion paints. They have universal properties and high performance, but they are much more expensive than their “counterparts”.
