Production of emulsion paint: What belongs in it?

Emulsion paints always consist of very similar components and yet they can have quite different properties. This is due to the variable combination of the individual raw materials, but also to the different qualities and quantity distributions. For example, a paint with many high-quality pigments better than a paint, which consists largely of fillers. Which ingredients are used in the production?

Binder as an important base material for the production of emulsion paint

The binder decisively influences the properties of a paint, its nature also depends on the choice of solvent. Emulsion paints usually contain a resin derived from mineral oil as a binder, this serves as an adhesive for the color, so to speak.

For modern wall paints, acrylic resins are usually used, which can easily be diluted with water. Similar resins such as polyvinyl acetate are occasionally found, especially in latex paints.

The most environmentally friendly solvent: water

Now comes a solvent added, in the case of the commercial wall paint is water. This is not only added in the preparation of the emulsion paint, but it also serves for further dilution by the user.

Water is the most environmentally friendly solvent, and each one contains pollutants in different concentrations and produces a corresponding odor in the liquid state. That's why emulsion paints are so well suited for interior coatings!

Especially important: the pigments

Without dyes, the color would not cover, so all emulsion paints include pigments. For a bright white usually provides the titanium dioxide, a non-toxic pigment with high hiding power.

Additives for the production of emulsion paints

Additives are additives that the paint manufacturer needs to vary the properties of a paint. Emulsion paints always contain fillers in varying amounts, for example calcium carbonate, quartz flour or silicates.

Because fillers are less expensive than pigments, low-cost manufacturers often replace part of the dye with bulking agents. This lowers the price, but also the opacity. Other possible additives:

  • thickener
  • Preservative: Fungicides / Algicides
  • stabilizers
  • defoamers
  • emulsifiers
  • decorative material such as glittering fabrics

Tips & Tricks

When buying inks, look for high opacity and abrasion resistance, and invest better in high-quality paint to avoid disappointment.
