TopCoat: Technology

Modern line technology for perfect quality

 

In the past users made different experiences with the quality of non-stick coatings. This lead to an unclear image so that in many cases coating have been called into question. We think that this was wrong.

The quality of coatings extremely depends on the coating technique used. In the past often the manual method by spraying pistols was chosen. But especially for high-quality PFTE, FEP and PFA coatings this method quickly reaches its limits.

With our TOPCOAT coating we clearly rely on the latest technology in order to keep the tight tolerances during processing. The safe preparation of the baking trays is as important as the actual coating itself.

The Anneliese – TopCoat – coating comprises following production steps:

  • Degreasing of the tray.
  • Pickling roughens the surface. Roughening the surface is the basis for a perfect grip of the coating afterwards.
  • 2 clear rinsing processes clean the tray.                   
  • One rinsing process with neutral water removes cristalline remainders.                                                           
  • All remainders of moisture are evaporated.                   
  • A first varnishing process primes the tray. Therefore this process is also called priming.                            
  • On 2 infra-red sections the tray is dried intermediately.                                                            
  • Then the TOPCOAT coating is applied.                     
  • On another infra-red section the material is dried again.
  • In an oven chamber dryer the TopCoat coating is burned in at 430°C max.

Permanent checkups guarantee safety.

Already the smallest changes in the basic substances may lead to problems during coating. A fully automatic control line checks every process and records all the line parameters and batch numbers. Thus we can exactly trace where a possible mistake occurred even a long time after production.
