Product Brief
High-Stability Aqueous FEP Dispersion HD923: Low-VOC, uniform coating & strong PTFE bonding. Excels in high-temp/corrosive environments, ideal for industrial coating, electrical insulation & composites.
Product Overview
HD923 is a premium water-based fluoropolymer dispersion, containing submicron FEP copolymer particles stabilized by non-ionic surfactants. It overcomes solid FEP's processing limits, enabling easy application on complex/porous substrates via coating/dipping. With low VOC emissions (RoHS compliant), it retains FEP's core advantages: 200°C continuous heat resistance, chemical inertness, excellent insulation, and low friction, serving high-performance eco-friendly coating needs.
Product Details
Key Properties
● Thermal Stability: 200°C continuous service, 240°C peak; C-F bond structure resists thermal degradation, outperforming acrylic coatings.
● Chemical Inertness: Inert to strong acids, bases, solvents; more stable than PVDF dispersions in harsh chemical environments.
● Electrical Insulation: Dielectric constant ≤2.15 (10⁶Hz), dissipation factor ≤7.0×10⁻⁴, suitable for high-voltage components.
● Dispersion Stability: Proprietary surfactants prevent aggregation for 6 months; ±5% coating thickness tolerance (ASTM D3159 verified).
● PTFE Bonding: Shear strength ≥1.2 MPa with PTFE, solving non-adhesion challenges for industrial assemblies.
● Eco-Friendly: Water-based, ultra-low VOC, compliant with RoHS/REACH; safe for high-volume production.

FAQ
1. Suitable application methods?
Spray, dip, brush, roll coating. Dip for porous substrates, spray for large flat metals. We provide detailed application guides.
2. Difference between Grade A/B?
A (0.8~5 g/10min, pH 7.0~9.0): thick coatings (≥50μm); B (5.1~10 g/10min, pH 8.0~10.0): thin coatings (≤50μm)/high-speed processing.
3. Can it bond non-PTFE substrates?
Yes, bonds metals, glass, PEEK. Light sanding for smooth non-porous substrates; no pre-treatment for porous ones.
4. Special curing equipment needed?
Conventional 300~380°C oven suffices. Cure time: 5~8min (≤20μm film), 10~15min (≥50μm film). Custom curing schedules available.
