Emulsions is made up of several different substances, these substances allow the paint to have specific properties and finishes when it is applied to surfaces.

Micro-Structure
|
Emulsions is defined as a suspension of small globules of one liquid in a second liquid with which the first will not mix, an example of these substances can be oil and water. In the case of making paint Emulsions, oil in water can be proportionally balanced so the paint will contain both oil and water. The reason behind mixing the substances in order to make paint Emulsions is to give the paint blendable and water resistant properties.

Ultrasound machine
|
Many companies use industrial machines to create the right mixture of Emulsions. Ultrasound is one of the used methods for mixing water based substances with oil based substances. When the unmixed liquid is placed in the machine, the high frequency sound generated from the device causes the oil and water substances in the liquid to mix, this creates a balanced amount of each substance in the Emulsions.

Emulsions paints are made up of tiny droplets of liquid polymer binder spread out in, rather than dissolved in water, this allows the Emulsions to be spread easily.
Stabilisers are sometimes added to the paint mixture to ensure that it stays balanced.
After an Emulsions paint is applied, the water evaporates and the polymer particles pack closely and fuse together to form a continuous film. The use of water rather than an organic liquid means that Emulsions paints produce fewer VOC (volatile organic compounds) when they are used.
Pigments are fine powders that are spread throughout the paint film and help hide the surface underneath and can also provide colour to the paint.

The final ingredients to be added into Emulsions paints are additives, small amounts of other compounds are added to paint to improve its properties. For example:
A compound to hasten the drying
A compound to prevent the formation of a skin in the can
Biocides stop bacteria growth in the water and thickener of Emulsions
Small amounts of titanium or zirconium compounds to the paints; they give the paint a gel structure rather than allowing it to flow like a liquid.
