As an industry that has been in existence for more than 50 years, powder coating has undergone a range of different trends. This technique first gained popularity because of its eco-friendly application process which does not require the use of any solvents. This was in sharp contrast to the previous method of improving the quality of metal substrate surfaces by wet painting them. Developed during the 1960s, powder coating combined the ability to distribute exacting amounts of pigments, binders and fillers in a coating process with a delivery method that is highly automated.
Improvements Within the Past Two Decades
Within the past 20 years, technological developments have lead to diverse processes that answer some of the challenges faced by manufacturers during that time period. These developments include paint systems that allow for protection from corrosion, pretreatment systems that utilize environmentally friendly wet chemical techniques and a reduction in the consumption of compressed air due to the introduction of powder applications that use dense powders — as well as a number of others.
New Technologies to Watch For
Conversion blasting allows for the application of chemicals to the substrate in question. It is combined with the right type of powder coating techniques so that an adequate amount of corrosion protection can be afforded without the use of a rinsing treatment that involves wet chemicals.
When it comes to pre-treating the substrate surface with wet chemicals, those that are free of chrome continue to make headway into the market. Many of the most popular of these chemical products contain zirconium, titanium or silane compounds. These systems are still being tested, as working with the new products that promise to further protect the environment brings up its own challenges and kinks that must be ironed out.
Ovens that reclaim heat are being used increasingly within the industry, and their use will continue to jump. By utilizing zones of upstream IR gels or radiation energy the process of curing the powder coating stands to become much more efficient. With the introduction of NT powder into the industry, there is a great deal of potential in the development of this aspect further. With this effort, a great deal of energy can be saved along with the corresponding costs of powder coating itself.
