We are a manufacturer based in China, specializing in high-quality Hyper-durable powder coatings for industrial clients worldwide. Technical support and custom formulation available.
Category：powder Coating | Brand：MT
Introduction
Hyper-durable powder coating — MT-D3020 Gen II — is a fluorocarbon polymer series built to AAMA 2605, the most demanding architectural specification. It is formulated for maximum gloss and colour retention in service, giving the cosmetic and functional protection of liquid PVDF (PVF2) in a technically and environmentally cleaner powder form. It is offered in a selected colour range with pearlescent effects in a subtle low-sheen finish.
Powder Properties
| Appearance / gloss | Smooth matt, 20–30 GU at 60° |
| Particle size / specific gravity | Suitable for electrostatic spray; 1.2–1.7 g/cm³ by colour |
| Storage / shelf life | Dry, cool, below 25°C; 6 months |
| Sales code | 8 series |
| Curing schedule (object temperature) | 30–40 min at 190°C · 20–30 min at 200°C · 15–25 min at 210°C. Do not cure above 210°C. |
Mechanical Tests
| Test | Standard | Result |
|---|---|---|
| Dry adhesion | AAMA 2605 §8.4 | Pass — no film removal |
| Impact resistance | AAMA 2605 §8.5 | Pass — no tape lift after 3 mm deformation |
| Dry-film hardness | ISO 2815 (Buchholz) | Pass |
| Abrasion resistance | AAMA 2605-13 §8.6 | Pass — abrasion coefficient > 40 |
Pre-treatment
For maximum protection, pre-treat components before application per the approved applicator guidance. Aluminium parts must receive a full multi-stage chromate conversion coating or a suitable chrome-free pre-treatment to clean and condition the substrate; confirm details with the pre-treatment supplier.
Cross-Contamination Control
Fluorocarbon powder must not be cross-contaminated with polyester or other chemistries. Recommended practice:
- Use a dedicated spray-to-waste booth if not reclaiming.
- Thoroughly clean booth, ductwork, cyclone and all application equipment (guns, hoses, pumps, hoppers) before and after; wipe the booth interior and feed hopper with a damp cloth.
- When returning to polyester after a fluorocarbon run, shoot foam blocks through hoses and flush guns with the next powder, then spray to waste before reclaiming.
- If reclaiming after a fluorocarbon run, check the reclaimed powder for contamination before reuse.
- Where possible, isolate the run — weekends or night shift when no other production is running.
- Operators wear dedicated protective clothing, stored in sealed containers; fluorocarbon powder may be stored alongside other powder as long as it stays sealed.
