Product Introduction:
This product series is a thermosetting powder coating made from saturated polyester resin, combined with corresponding curing agents, pigments, fillers, and other specialized additives. It features excellent weather resistance, UV resistance, and thermal stability.
Product Applications:
Suitable for surface coating and protection of electrical equipment, sports equipment, automotive components, aluminum profiles, electrical cabinets, and other metal surfaces.
Powder Properties:
experimental project | technical indicators | remark |
specific gravity | 1.4~1.8g/cm2 | Different in formula and color |
Fineness determination | Different in variety and purpose | |
180 mesh sieve residue | <0.5% (flat powder) | |
160 mesh sieve residue | <0.5% (art fans) | |
Coating Appearance:
category | gloss | surface effect |
Highlight class | ≥90% | Flat and smooth, sand texture, wrinkles, orange peel texture, floating color patterns, cotton texture, hammer texture, metallic luster, metal composite, thermal transfer powder can also produce antibacterial coatings, reversible safety temperature-indicating coatings, and other special requirements are manufactured according to customer samples |
Flat light category | 60~85% |
Semi luminous class | 25~45% |
No light class | 3~10% |
Note: The gloss is measured according to the GB1734-79 standard using a 60° angle gloss meter.
project | Reference standards | indicator |
impact test | CB/T 1732-93 | 50kg/cm2 |
adhesion | CB 1720-79 | Level 0~1 |
Bend Test | CB/T 1732-93 | ￠1~2mm |
pencil hardness | CB 6739-86 | H~2H |
Note: Produced according to customer requirements. All tests were conducted using the CB1727-92 standard for sample preparation, with a film thickness of 60-80um, completed under laboratory conditions.
project | Reference standards | indicator |
salt spray test | GB1771 | 500n no change, cross-sectional corrosion less than 2mm |
Damp Heat Test | GB1740 | The 1000n coating remains unchanged with slight loss of gloss |
Note: All tests were performed using samples prepared with degreasing, derusting, and zinc phosphating, with a film thickness of 100-120um, completed under laboratory conditions.
project | workpiece temperature | curing time |
low-temperature curing | 160°C | 10~30min |
Medium temperature curing | 180°C | 15~25min |
rapid curing | 200°C | 5~15min |
Note: The recommended curing conditions refer to the workpiece temperature. Temperature deviations may affect paint performance or prevent full potential from being realized.
