XGE-HY-(A, B)Water-based epoxy antirust primer grey
Water-based Epoxy Anti-rust Primer · Category: Transmission tower
Two-component water-based epoxy anti-rust primer formulated with advanced emulsion technology. Excellent adhesion to blasted steel, outstanding salt spray resistance, and low VOC for environmentally responsible corrosion protection of structural steel and industrial equipment.
Key Features
- 240-1000 hours salt spray resistance (depending on topcoat system)
- Excellent adhesion on sand-blasted steel (Sa 2½)
- Low VOC (< 50 g/L), water-based, low odor
- Compatible with both water-based and solvent-based topcoats
- Fast dry-to-recoat, suitable for shop and field application

Application Notes
Surface preparation: Remove all oil, grease, dirt, and loose rust. Abrasive blast to Sa 2½ (ISO 8501-1) for best results, or power tool clean to St 3 minimum. Apply on dry surface with substrate temperature at least 3°C above dew point.
Mixing: Stir component A thoroughly, then add component B (if applicable) in the correct ratio. Mix with mechanical stirrer for 3 minutes until uniform. Pot life varies by product, typically 2 hours at 25°C.
Application: Airless spray is recommended for best results. Brush or roller suitable for small areas and touch-up. Apply in even, wet coats to specified DFT. Do not exceed recommended film thickness to avoid sagging.
Storage & Safety
Store in original sealed container between 5-35°C, away from direct sunlight and freezing. Shelf life is 12 months from date of manufacture in unopened container. Refer to product SDS for detailed safety, handling, and first-aid information. Use appropriate PPE during application.
