Use as an alternative to the traditional liquid paint that many of us know, powder coating makes use of an advanced process where finely ground particles are electrostatically charged and sprayed on the surface of the object to be coated. The result is a hard and durable finish that is considerably better than what can be done with conventional liquid paint. Why is it environmentally friendly?
Advantages of Powder
In powder coating, the parts have to be heated so that the powder can be melted to create a coat that will chemically and physically bond with the material’s surface. The great thing with this type of coating method is that the surface becomes almost scratch-, fade-, and chip-resistant. It is comparatively stronger than conventional paint, which means that it lasts longer and does not require recoating for a significant number of years.
Once it has sprayed on the surface of the material to be coated, it will be placed in a giant oven where it will be baked. The powder particles will be melted by the heat and fuse with the surface resulting in the smooth coat. The finish is equally attractive, uniform, and safe. So why is it considered environmentally safe? Because of the following reasons:
- It has no Volatile Organic Compounds (VOCs);
- No solvents are used, reducing the risk of fire and allowing for better waste disposal;
- Generates less waste;
- Recycling of the powder can be done using extraction systems;
- Shorter processing time for the powder;
- Operators are not at risk from the materials;
- Newer powders can be cured at lower temperatures to conserve energy; and
- Some types of powder coatings have higher chemical and physical resistance resulting in reduced transportation and storage cost.
Friend of the Environment
The powder coating process was initially used during the 1960s in Australia. This process used for coating metal structures is considered comparatively friendlier to the environment as against conventional liquid coatings and traditional powder coatings.
Because of the advantages stated above, it does not pose danger to human health or directly harms the environment. Even if it is over sprayed, it can still be recycled. This means that as much as 92% of the coating can be used with only a small percentage considered a waste.
The waste material is less hazardous to that produced by conventional liquid coatings. This means that it will not cause harm even to water supplies because there are no heavy metals involved like cadmium and lead for example. There is no waste water discharge directed to public sewers, ground water, or even the earth’s surface.
In terms of carcinogenic substances or agents, there is none. So the cells of the operators will not develop cancer even if exposed to powder coating for an extended time. The by-products of the process are as harmless as the actual powder coating process itself.
Affordable and Effective
Aside from being environmentally friendly, the entire powder coating process is also kind to your wallet. This is because as a durable coating, it can last for a considerably long time, which means there is no need to repeat the process at once.
It also does not require several coats to get a smooth and shiny finish, unlike paint. So, you save from the amount you have to pay for the powder. You also do not have to wait for a long time as powder coating can be finished in as fast as an hour. There is no problem when it comes to color, texture, and effects. Powder coating can offer a lot of options that you cannot get with paint. This means less amount of travelling from one store to another to get the perfect match. So you save on gas as well.
