Key Properties
- Pre-Catalyzed Formula
- Eliminates need for additional driers during paint formulation, simplifying production processes.
- Performance Advantages
- Low VOC emission | Gloss level ≥90° (60° GU) | Hardness: 2H (pencil test)
- Rapid drying: Tack-free within 30 mins @25°C | Salt spray resistance: 500+ hours (ASTM B117)
- Shelf stability: 6 months without sedimentation (viscosity change <10%)
- Pigment Compatibility
- Superior shear stability (Brookfield viscosity <200 cP) enables direct grinding into color pastes.
- Optimal dispersion: Hegman fineness ≤10 μm
- pH Sensitivity
- Stable at pH 8.5–9.5 | Precipitation risk in acidic environments (pH <7)
- pH adjustment: Compatible with organic amine-based stabilizers
Applications
Primary Use: Corrosion-resistant primers/topcoats for:
- Automotive Components: Chassis, brake systems, gearboxes, motors, EV battery casings
- Industrial Equipment: Hydraulic cylinders, CNC machinery, transformer housings
- Infrastructure: Structural steelwork, offshore pipelines, railway components
Emerging Markets:
- Zinc-rich coatings for galvanized substrates
- Renewable energy systems (wind turbine fasteners, solar mounting hardware)
Storage Guidelines
- Temperature: 0°C to 40°C (crystallization risk below 0°C)
- Shelf Life: 6 months in sealed containers (test batch required post-expiry)
- Avoid acidic contamination during handling
