Test instruction TIGER DRYLAC Quality Control Powder coating of test sheet metals PA 08 Approved by: Ing. Mathe Issue date October 2001 Update status 08 Folder - Nr HQ 03 - 18 page 1/2 1. Purpose / Target: The conditions are to be determined for coating test sheet metals with powder coatings. 2. Description of the procedure: Testing sets: cup pistol warming cupboard cabinet coating Cab system parameters The system adjustments for the coating are: - Voltage : 50 - 60 kV - Incoming air : 4 - 6 bar - Dosing air : 4 - 6 bar Execution The powder sample is filled into the cup of the pistol, and the required sheet metals are coated with the film strength stated below. With system attempts and pallet samples only a non- chromated box sheet metal is coated. The powdered sheet metals are burned with the burning conditions given in the table (temperature, time) in a circulating air drying furnace. After the cooling the sheet metals will be provided with the filled out labels (system attempt and pallet samples: with the label of the machinist).
