| Product Description | MP epoxy/polyester thermosetting powder coatings consist of a series of epoxy/polyester blended powder coating products, designed for indoor use. MP epoxy/polyester thermosetting powder coatings can be supplied in a wide range of colors, different surface gloss levels, and various surface texture effects to meet customer needs. |
| Powder properties |
Specific gravity: 1.2-1.8 (varies depending on color) Particle size: Suitable for electrostatic spraying Storage conditions: In a dry, cool environment below 30°C Storage life: 6 months Curing conditions: 200°C/10 minutes or 180°C/15 minutes (workpiece temperature) |
| Coating performance | Mechanical properties were tested using samples that had undergone degreasing and zinc phosphating treatment, with a film thickness controlled to 60-80 micrometers, and cured by baking at 200°C for 10 minutes (sample temperature). Chemical properties were tested using samples that had undergone degreasing and zinc phosphating treatment, with a film thickness controlled to 100-120 micrometers, and cured by baking at 200°C for 10 minutes (sample temperature). A decrease in product gloss may lead to a decrease in mechanical properties. |
| Mechanical performance testing |
Bending performance: Product gloss: ≤60°, ≤4mm Product gloss>60° 2mm Adhesion: GB9286 Level 1 Cupping test: Product gloss ≤60°, indentation depth ≥4mm Pencil hardness: GB/T6739 ≥1H Impact (positive/negative): Positive impact |
| Chemical performance testing |
Neutral salt spray resistance test (500 hours): GB/T1771, not
exceeding Level 1. Humidity and heat resistance test (500 hours): GB1740 Not greater than level 1 Solvent/Chemical Properties: Under normal temperature conditions, it exhibits some resistance to acids, bases, and oils. |
| Preprocessing |
Before using MP epoxy/polyester thermosetting powder coatings, the
substrate requires pretreatment. To achieve optimal film
performance, the following pretreatment methods are recommended.
Pretreatment should be carried out according to the supplier's
instructions.
Aluminum material: phosphochromate treatment Galvanized steel sheet: Zinc phosphating Standard steel plate: zinc phosphating or hot phosphating |
| Application | MP epoxy/polyester thermosetting powder coatings are suitable for application with electrostatic spray guns. We can also provide MP epoxy/polyester thermosetting powder coatings that meet the requirements of friction gun systems. Oversprayed powder coating can be recycled during the application process. |
