Powder Coating for Entry Doors

5/21/2018

​These are the two main reasons why Groke uses only powder coat finishes for its aluminum entry doors.
  • Performance: Powder coated products are more resistant to chipping, scratching, UV rays, and corrosive elements. This process uses a dry powder of polymer resins, pigments, leveling agents, and other additives that is ground into a uniform powder similar to baking flour. Electrostatic spray deposition (ESD) is used to apply the powder coating to the metal product. A spray gun with an electrostatic charge is used to apply the powder particles which are attracted to the grounded metal. After application of the powder the material enters a curing oven where with the addition of heat the coating chemically reacts and forms a “skin” on the material. This thermal bonding allows for a more uniform coverage no matter whether you have a horizontal or vertical surface. The powder coat bonding is much thicker than standard wet paint, which is generally no more the .5 to 1 mil in thickness (a mil is one one-thousandths of an inch). Powder coat finishes range from 2 mil to 10 mil in thickness.

  • Safety and Sustainability: Because the powder coating process does not require a liquid carrier (solvent) like liquid coatings this system emits near zero volatile organic compounds (VOCs). This means powder coating is environmentally friendly since no VOCs are released into the air. Moreover, powder coating is a clean process because powder overspray can be retrieved and reused. Unused powder can be reclaimed and returned to the hopper for recirculation through the system, with negligible waste.  Plus most powder coat materials are considered non-hazardous material and landfill safe. Powder coating meets all Environmental Protection Agency (EPA) requirements for air and water pollution control.
