Acrylic paint is mostly water based, it can be used as a facade and as an interior. It is based on polyacrylates, pigments and water. The macromolecules in it are folded into particle balls, which form a dispersion with water. Polyacrylic polymers are used as a binder and film-forming substance.
Composition and properties of facade acrylic paint for walls
The first and main component of any acrylic paint is a film-forming binder. It gives the paint its main characteristic - the ability to good adhesion with the surface to be painted. Also, this substance binds all the pigments and fillers together, making the paint uniform and usable.
The second component of acrylic paint for facade works is a pigment, which is a finely dispersed particles, absolutely insoluble in disperse media. This element of paint gives it color, opacity, strength, anti-corrosion properties. In other words - decorates and simultaneously protects the painted surface.
Also in the composition of acrylic paints for facades include various fillers that can provide it with additional physical properties: gloss, mattness, strength, water resistance and so on.
In addition, the paint has some additional substances, for example - emulsifiers, thickeners, dispatchers, etc.
Acrylic exterior paint differs between each other, depending on the type of dispersion medium. It can be not only water, but also acrylic lacquers or rasters of acrylic copolymers (BMS-86).
Technical characteristics of facade acrylic paint
In a few words, the properties and technical characteristics of this type of paints can be described as follows:
- Coating strength;
- quick drying;
- suitability for use on porous surfaces;
- water and vapor tightness;
- resistance to temperature changes and atmospheric phenomena.
