What Is a Synthetic Resin Emulsion Paint?
Synthetic resin emulsion paints are liquid paints that use water as a base in which synthetic resins are dispersed as fine particles.
Since this paint uses water as a solvent, emissions of volatile organic compounds (VOCs) are low, making it an environmentally friendly paint. In addition, the dried paint film is durable and easily adheres to a variety of surfaces.
Applications of Synthetic Resin Emulsion Paints
1. Painting of Interior Walls and Ceilings
Synthetic resin emulsion paints are widely used for painting interior walls and ceilings of residences and commercial facilities because of their smooth finish and rich color variation. Their beautiful finish and environmentally friendly properties create a comfortable living environment.
2. Painting Furniture and Wood Products
Synthetic resin emulsion paints are also suitable for painting wood and wooden furniture. Their durability and uniform finish protect furniture and wood and extend their service life.
3. Interior Decoration
Synthetic resin emulsion paints are also used for interior decoration due to their wide color variation and beautiful finish. In particular, they are used as an option for accent walls and design walls to create unique and attractive spaces.
4. Public Facilities and Commercial Facilities
Synthetic resin emulsion paints are also used for wall and ceiling paints in public and commercial facilities such as schools, hospitals, and office buildings. The paints combine durability and aesthetics to provide a comfortable environment.
5. Hotels and Restaurants
Synthetic resin emulsion paints also play an important role in the interior design of hotels and restaurants. They are used to create unique atmospheres and ambiance with a wide variety of colors.
6. Arts and Crafts Activities
Synthetic resin emulsion paints are also suitable for arts and crafts activities. Their simplicity of application and ease of handling support individual creative activities.
Principle of Synthetic Resin Emulsion Paints
Synthetic resin emulsion paints are made by dispersing tiny oil droplets (resin particles) in water. The resin becomes microscopic particles in the water, which form a homogeneous mixture. The resin particles are electrically charged and are dispersed while repelling each other.
Note that an emulsion is a phenomenon in which two phases (usually a liquid and a liquid) mix uniformly as a fine dispersed phase and a continuous phase. In this case, the continuous phase is water and the synthetic resin is dispersed as fine particles in the dispersed phase. This forms a stable dispersion of the synthetic resin in the water phase.
On surfaces where synthetic resin emulsion paints are applied, the continuous phase evaporates from the emulsion state as the water evaporates and the fine synthetic resin particles come into contact and fuse. This forms a continuous film of synthetic resin. This film covers the surface as a coating film and a beautiful appearance and protective properties can be achieved.
Types of Synthetic Resin Emulsion Paints
1. Acrylic Emulsion Paint
Acrylic resin-based paints are suitable for a wide range of indoor and outdoor applications. Because of their high durability and resistance to fading, they are widely used for painting exterior walls and wood. It is also water-based, which makes it environmentally friendly.
2. Vinyl Acetate Emulsion Paint
This paint is mainly composed of vinyl acetate resin and is suitable for painting wood and wallpaper. It is flexible and has excellent elasticity, so it can respond to shrinkage and expansion of materials due to seasonal changes.
3. Urethane Emulsion Paint
This paint is made from urethane resin and has high durability and gloss. It is suitable for the protection and decoration of wood and metal surfaces and has the performance to withstand the external environment.
4. Epoxy Emulsion Paint
Epoxy resin-based paints are used on metal and concrete surfaces. This type of paint has excellent corrosion and abrasion resistance and is widely used for industrial applications and floor coatings.
Other Information on Synthetic Resin Emulsion Paints
1. Production of Synthetic Resin Emulsion Paints
When manufacturing synthetic resin emulsion paints, the dispersion of the synthetic resin must be stable. Surfactants prevent resin particles from attracting each other and support uniform dispersion within the dispersion phase. This maintains the resin particles in a stable state in the aqueous phase without agglomeration.
2. Formation of Synthetic Resin Emulsion Paints
Synthetic resin emulsion paints are formed when the dispersed phase and the continuous phase (aqueous phase) mix in an emulsion state. This is a state in which fine synthetic resin particles are uniformly dispersed in the aqueous phase. This paint forms the basis for a uniform film when applied.
