Spray paint is stored in a pressurized and sealed container and released only when the valve is pressed. It’s a combination of paint and a gas propellant. The cans are first filled with paint during the manufacturing process and then injected with the gas propellant. At last, the valve is crimped, trapping the highly compressed compound within the confines of the can.
Spray painting is a modern way of painting devised to make work easier and avoid wastage of paint. It creates a smooth and even film of paint more than its traditional counterparts brushed and rolled paints. In addition, spray paint is inexpensive, lightweight, easy to store, and portable. Spray paint can also be used on plastics and metals directly.
What is Powder coating?
Powder coating refers to a dry finishing process. This method was launched in North America in the 1960s and has become one of the most preferred finishing methods across the world. It represents a 15% share of the industrial finishing market. Powder coating can be used in a wide variety of products. It is also available in many types of color shades and textures for decorative and functional protective finishes.
The main ingredient for powder painting is polymer resin systems combined with leveling agents, curatives, flow modifiers, pigments, and other additives. All these ingredients are melt mixed, then cooled down, and finally ground into a uniform powder. This powder is applied using electrostatic spray deposition. It is done using a spray gun that charges the powder particles with an electrostatic charge. Once it is sprayed onto a surface, it has to pass through a curing process.
Powder coating vs spray paint
Both powder coating and spray paint have advantages and disadvantages. There are some instances where powder coating performs better than spray painting and vice versa.
Spray paint offers more even coverage without brush strokes, which is easier to apply on plastics, auto, and furniture with spindles, small pieces, or intricate nooks and crannies. In addition, it is the best choice for DIY projects. Spray paint does not require to undergo a curing process because it dries on its own. It is the best option to use for items that require a thin paint coat. Lastly, spray paint is affordable since it does not require high-tech equipment.
Powder coating is best for metal surfaces. The curing process involves heating the surface hence surfaces like plastics and wood are not recommended. However, it creates a thick and adhesive coating that is durable compared to typical paints. Another benefit of using powder coating is that the process is very efficient and fast. The results will be a consistently smooth and solid surface with no painting marks. One of the major drawbacks is that you need high-tech equipment.
