10 Signs You Should Use Powder Coating Rather Paint | Tips & Tactics
Powder Coating Vs Paint
In the world of aircrafts there are powder coats or spray which have many advantages. But what exactly is the difference between powder coating and painting? Let’s just get through this difference first.
Working of Powder Coating?
It is a color finishing technique in which instead of paints powder is used which is applied by spray tools and heated to the chosen surface to form a color coat. Many ingredients can be used as a powder for processes such as acrylic, polyester, epoxy, and many more. As it achieves many thick and consistent finishes compared to spray paint. Powder coat sprays can be available for light-duty applications. Cost-effective services of Powder coating in Ahmedabad and it is seen in everyday appliances and household fixtures for example stoves, refrigerators, tables, and many more. And it is also quite common in the finishing stage of auto assembly.
It is only achievable by thermoplastics or thermosets. If we use thermosets chemical additives which interact with powder during the application stage. And the end result of both are virtually identical and in the process, you heat the powder to form the color finish for the chosen surface.
Steps involved in powder coating a material:
- In the first stage, you must have to choose a surface to ensure proper adhesion of the finishing. For industrial applications, you have to clean the surface, usually a metal of any oil or dirt that would hinder the usage of powder.
- During the application, stage powder is transformed and brought to the stage of adhesion with a chosen surface which is known as the electrostatic process in which powder granules and surface jointly charged with volts of electrostatic energy
- And once powder coating is applied the finish should cure for 10 minutes at an excess heat level of 400°F which allows the newly melted powder to settle for the chosen surface. As the finish sets the original property of polymer, acrylic or epoxy comes to bear fruits in the form of a tight, thick, and shiny surface coat.
As compared to spray paint application powder coat is more efficient due to the electrostatic process which reduces waste by 95%. The majority of color granules that go into powder coat application which arrive at their intended destination and the amount which can’t be reused goes to later application.
Another process is also there which is called electrostatic painting and both the processes are based on similar concepts the only difference is that it does not need to be baked to cure. Electrostatic paint uses an electrical charge to bond the paint to metal.
Consider with Powder Coating Materials:
- Liquid paints have many offers while powder coats have very limited options. As some powder manufacturers which can create any color in powder form while others are restricted to some of the basic colors
- We should consider the labor requirements and the access to the material such as custom-ordered powder coats colors
- The standard should be compliant with the 9001:2008 standard from the International Organization for Standardization which helps in good quality and manufacturing practices
- We should also consider the operation overall supported by the suppliers and the equipment and coating material should come from a trustworthy and reliable person
We should also consider buying materials from a trustworthy person which is found in Ahmedabad.
Working of Spray Paint:
Industrial color coats are achieved by a self-explanatory process known as spray painting where paint is applied in aerosolized form through a pump device at very high pressure. Before applying a coat of spray paint the chosen surface should clean the metal of oily residue and dirt. Then you can treat the surface to a wet blast of roughly 15 – 20 minutes and the process continues till it has evenly coated the entire surface with a sufficiently thick layer of paint. Benefits:
- Wet paint dries by its own and does not need anything to wet this and so you can apply it to products that cannot submit to hear treatments
- Paints can be in many ranges of colors than powder and it is useful for many varieties of products and signage
- Wet paint can apply thinly to a surface and would leave a smooth texture which makes it the more suitable option for items that require thin coats
- The tools required for the spray painting process are simple to use and more affordable than powder coating.
Which is Better: Powder Coating Vs. Paint?
- The first factor which is taken into consideration is efficiency with a general transfer efficiency of 60-70% with roughly two-thirds of powder used for a given application serving the intended purpose whereas paint has a transfer efficiency of only 30- 35% and waste two-thirds of paint used for given applications. The leftover is taken into account which is not lost with the powder applications. Once the coat has been completed the percentage of powder that falls aside can be collected and put back to use in the very next cycle.
- Powder coating is a safe process because of the active product which are polymer powder that is inserted and is free of toxins. Whereas paint usually has toxic solvents and volatile organic compounds which can be harmful if inhaled.
- Since in polymer powders, there are no volatile organic compounds and toxins and whether used or unused the unused portion does not emit greenhouse gasses. The majority of given powder supply goes to put to use the only easy option is to on landfills whereas application of spray paint send toxins to atmosphere
- While both can help to achieve a glossy finish it is much easier to do with liquid paint. Thin powder coats are more textured and they will feel like the skin of an orange.
- Powder coats take a short time unlike paint which may need days to get fully dry and powder will fully cure in 20 minutes or less.
