Teflon Coating "Processing Methods and Processing Steps"

What is the processing method for Teflon coating? Here, we will introduce the processing methods (steps) to ensure adhesion between the substrate and Teflon resin.

Non-stick properties of 'Teflon coating' require a special processing procedure to ensure adhesion to the substrate. 【Overview of Processing Steps】 ■ Substrate Acceptance ○ Inspection of the substrate will be conducted. ○ If there are any issues that may hinder processing, we may request corrections. ■ Degreasing Treatment ○ Cleaning the substrate of dirt and oil using solvents. ○ Heating the substrate in a furnace to thermally decompose fats and contaminants. ■ Pre-treatment - Blasting ○ The processing surface is blasted to remove rust and dirt, and to create a suitably rough surface. - Etching and Chemical Coating Treatment ○ Pre-treatment is performed according to functionality when blasting is not feasible. ■ Primer Coating ○ A primer is applied to enhance adhesion between the substrate and fluoropolymer. ■ Baking ○ Curing of the primer is performed. ■ Coating - Powder Coating ○ Fluoropolymer powder is applied using a special coating machine. - Enamel Coating ○ Fluoropolymer enamel is applied either by machine or manually. ■ Baking ○ The fluoropolymer is heated and melted to form a coating film. ■ Inspection ○ After processing is completed, we inspect to ensure that the work meets specifications and agreements.
