Poor Adhesion Of The Powder Coating 1. Workpiece surface degreasing, rust removal.phosphating and other surface treatment is not good Solution: Strict control of workpiecesurface treatment process 2. lnsuffcient curing Solution: Pls reference the last blog 3. Base

Why After Spraying Has Poor Leveling Performance, With Obvious Orange Peel? 1. Coating is toothick or too thin Solution: Control the coating thickness by adjusting the coating equipment2. Baking temperature is too low Solution: Adjust the baking temperature to the correct value

1. The coating film is too thin lncrease the coating thickness of the coating film 2. Uncleanspraying environment The spraying room should be clean, the air should be purified, and theworkshop should be kept clean. 3. Unclean baking environment (A) control the amount of air

Solution of Bubbles or Pin-holes in epoxy coatings?1. Workpiece degreasing and rust removalis not complete or phosphating after washing is not clean The strict control of surfacetreatment quality 2. Moisture not thoroughly dried after surface treatment Appropriately

1. Excessive baking time Shorter baking time, our standard time is 200'C/10Mins 2. Excessivebaking temperature Lower baking temperature 3. Uneven coating thickness Pls reference.4. Unclean air in the oven Check air heating system and exhaust air 5. Powder formulation needs

1. Pre-treatment Sandblasting and sanding to ensure that the workpiece is free of oil andembroidery. 2 . Theoretical curing conditions of powder coating A. Theoretical curing condition130°C/20min. 160°C/15min. 180°C/10min. 200°C/5min. B. Temperature is the actual
