Technical Data Sheet

Water-based epoxy antirust primer grey

Water-based Epoxy Anti-rust Primer · Category: Telecommunication 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

Typical Applications

Structural steel
Bridges
Industrial machinery
Storage tanks
Pipelines

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)
