\n Why powder coating is a key technology for modern industry <\/h2>\n <\/div>\n <\/div>\n\n
\n
\n
\n

Powder coating is an advanced coating process that uses thermosetting or thermoplastic painting powders applied electrostatically and then cured in an oven.<\/p>\n<\/h3>\n <\/div>\n <\/div>\n

\n
\n

It is a high-performance, versatile, cross-industry technology chosen by many industries for its ability to combine aesthetic quality, mechanical strength, production efficiency, and environmental sustainability.<\/p>\n

Thanks to its ability to precisely treat materials and components of varying complexity, powder coating finds application in sectors such as metal furniture, window and door frames, ACE, heavy carpentry, Energy and Oil&Gas. In the most demanding industrial applications, the most popular technologies include epoxy powder coating, which is particularly appreciated for its high chemical and anticorrosive resistance. <\/p>\n <\/div>\n <\/div>\n \n <\/div>\n\n <\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n\n

\n
\n

Powder coating, in its complete production cycle, involves three stages: pretreatment, application, and curing, each essential to achieve a homogeneous, durable coating that meets the quality standards required by modern manufacturing.<\/h3>\n<\/h3>\n <\/div>\n <\/div>\n
\n
\n

Surface preparation or surface pretreatment<\/h4>\n

It consists of removing contaminants<\/a>, oxides and residues by phosphating or sandblasting<\/a>. This step is crucial to ensure adhesion<\/a> and durability of the coating.<\/p>\n

Application of painting powder<\/h4>\n

It takes place through manual electrostatic guns or through the automatic systems integrated in spray booths. Transfer efficiency and easy recovery of excess powder are key factors in optimizing the performance of the powder coating process and guide the choice of the most suitable system.<\/p>\n

Polymerization in the oven<\/h4>\n

Baking in static ovens transforms the powder into a continuous, strong and durable film. Temperatures and timing vary depending on the material and type of coating, such as in epoxy powder coating used for high anticorrosive performance.<\/p>\n

Then there are different application technologies, which vary according to production needs:<\/p>\n
