What Is an Emulsion Paint?
Emulsion paint is a liquid in which particulate resin is uniformly dispersed in a solvent. The solvent is basically water, and solvents are rarely used today. Since it is water-based, it can be freely diluted with water, and its viscosity can be easily adjusted with a thickening agent. It is easy to apply even to highly hygroscopic surfaces such as mortar, and pigments and additives can be easily mixed.
On the downside, it is prone to mold growth, freezing at low temperatures, and extreme viscosity. Compared to paints that use solvents, it is inferior in adhesion.
Uses of Emulsion Paints
Emulsion paints are mainly used as architectural paints. Commonly used resin types include acrylic, acrylic styrene, urethane, fluorine, vinyl acetate, and ethylene-vinyl acetate copolymer resin.
Under harsh conditions, acrylics and other resins with excellent weather, water, and alkali resistance are used, while thermosetting acrylic emulsions are sometimes used for metal coating. Baking is performed after painting to induce a cross-linking reaction to improve hardness, adhesion, and resistance to water and solvents.
Principle of Emulsion Paints
First, emulsion particles dispersed in water are brought close to each other by the painting process and are packed tightly together.
As the water evaporates, the protective layer on the surface of the particles is destroyed, and cross-linking progresses on the exposed polymer surface, gradually resulting in adhesion.
The adhered particles form a uniform film, which becomes a pigment-filled coating film.
If the drying temperature is below the minimum film-forming temperature, the particles will not deform and adhere, resulting in a powder that is not strong enough. Therefore, auxiliary agents are added to facilitate the reaction.
Since most emulsions cannot be restored to their original state once frozen, ethylene glycol is added as a freezing stabilizer or copolymerization of hydrophilic monomers is used to stabilize the emulsion. Dispersants, thickeners, stabilizers, and anti-fungal agents are also added as needed to stabilize the quality of the paint during storage.
In addition, mechanical strength is often higher after a certain period than immediately after film formation. This is because polymer diffusion continues after film formation.
Reasons for Emulsion
Coatings are applied for the purpose of beautifying and protecting surfaces, such as workpieces. Because of the abundance of water as a solvent on the earth, it is common to use colored oil-based liquids that do not blend with water to prevent the painted surface from being damaged by water.
When oil-based liquids are used, there is a risk of ignition or fire in the vicinity of fire, and care must be taken to handle them in accordance with the laws and regulations. Therefore, emulsion paints are made by applying emulsion technology, in which oil droplet particles are suspended in water, to disperse oil-based pigments. Since the main ingredient is water, there is no risk of fire, it is easy to dilute and adjust viscosity, can be applied evenly, and can be sprayed.
Advantages and Disadvantages of Emulsion Paints
The advantage of emulsion paint is its low impact on the human body. After oil-based paint is applied, the solvent component evaporates and the paint film hardens. If a person inhales the paint, he or she may feel sick and lose consciousness. Even after the paint dries, a small amount of solvent remains in the paint film, which can cause health problems such as sick building syndrome. Emulsion paints, on the other hand, do not adversely affect health because all that evaporates is water.
The disadvantage of emulsion paint is the adhesion of the paint film is poor compared to oil-based paints. Since the paint is suspended in water, it is more hydrophilic than oil-based paints, and the paint tends to peel off easily on exterior walls and other areas exposed to rainwater. In exterior wall paints, this disadvantage is compensated for by applying several layers of paint.
Trends in Emulsion Paints
Sixty percent of emulsion paints are used for architectural applications. This is because, compared to oil-based paints, emulsion paints contain less VOC (volatile organic compounds) and can be used to prevent sick building syndrome. The switch from oil-based paints is expected to continue in the future.
