1. Appearance identification method of thermosetting powder coatings: 1. Touch: rough and fluffy hand, heavy hand, smooth touch, and good overall quality; 2. Volume: the larger the volume, the higher the cost and the better the quality. 3. Storage time: Thermosetting powder coatings that can be stored for a long time have stable performance, are not suitable for deterioration, and are of good quality.
2. Method for identifying the spraying area of thermosetting powder coatings: Select two thermosetting powder coating products and spray the same equipment. If the number of sprayed parts is large and the cost is low, it is a relatively high-quality product; the working efficiency of thermosetting powder coating sprayers : Observe the powder application efficiency of the construction workers, high-quality thermosetting powder coatings, fast powder application, less secondary recycling, spraying 13 guns can cover all the substrates, greatly improving work efficiency, at least poor quality To spray 3 to 5 shots.
3. Appearance recognition method of finished thermosetting powder coatings: Thermosetting powder coatings with full, delicate, three-dimensional and transparent finished products are high-quality products. Such powder products not only have excellent visual perception, but also maintain a relatively high quality. Long gloss, unlike poor quality paint that starts to fade after a few months.
Fourth, the method of identifying the adhesion and aging speed of thermosetting powder coatings: good adhesion, the paint film is difficult to damage, even if it will not age for a few years, powder coatings that are powdered are high-quality powder products, aging, rusting, powdery The faster the melting, the worse the product quality.
