What Is An Emulsion Paint And Why Did You Use It Mainly On Walls?

It is made up of acrylic resin, and other resins like SB-Latex and Polyvinyl Acetate, etc. In the form of an emulsion, it acts as a binder or adhesive on the surface. Any paint needs an adhesive to stick to the surface. The paint contains pigments that give it colour and protection from UV light, solvents that either dissolve part of it or improve the flow of the paint, and finally various additives such as anti-aggregate agents, anti-resisting agents, and surfactants.

An emulsion is a constant suspension of the oil phase in the aqueous phase. It is known by experts that oil and water do not mix. Some surfactants are added to improve the stability of the oil suspension in the water. In the case of acrylic paint, the acrylic resin having an oily phase, along with the finely ground pigments present in it, is kept in a water suspension. For this purpose, special surfactants and emulsifiers are used. Typically about 50 to 60% of complete water is available in emulsion paints. The remaining oily parts and solids in the form of pigments. However, it must be remembered that dyes have a higher density than water, and water is less proportional to weight.

 

When you apply this paint to a surface, the water evaporates and leaves the oily acrylic resin on the surface. Acrylic paint can be dried by evaporating solvents only in the case of thermoplastic acrylic resin. However, modern technology has introduced self-crosslinking acrylic polymers and cross-linking agents to dry acrylic resin in a 3D mesh. This results in cross-linking of the acrylic, leaving a tough, scratch-resistant coating.

 

Concerning the question of why it is applied to walls alone, the following factors must be considered:

The acrylic emulsion contains more than 50% water and is diluted to make it flow better. If there is a lot of water in it, it is essential for the water to leave the system faster once it is applied. If the water remains for a long period of time, the paint may not dry out, and the acrylic resin may or may not get stuck. Walls and panels with cement or plaster of Paris are best for it. The cement surface is porous and quickly absorbs water. Therefore, it is usually applied to walls or cement board panels

First, the paint is a mechanical mixture in a liquid medium that dries when applied to any surface to form a solid film. Latex paint is an acrylic resin, and the pigments are dispersed in water, and water is the solvent that carries the solid components (resin and pigments). The water evaporates, leaving a solid colour film.
