2K water-based epoxy topcoat with chemical, acid, alkali and moderate solvent resistance for steel structures, ships and machine tools. Low-VOC, easy application on steel, wood and concrete. Sa2.5 prep, 50µm DFT per coat.
Overview
Two-component waterborne epoxy anti-corrosion topcoat for steel, wood, and cement surfaces requiring chemical and abrasion resistance.
Composition
Waterborne epoxy resin dispersion and curing agent with pigments, additives, and functional fillers; supplied as Part A & Part B.
Typical uses
Anti-corrosion topcoat for various steel structures, wood and cement products, as well as surfaces of ships, machine tools, and electrical equipment for protection and decoration.
Technical data (typical)
Appearance: various colors.
Density: 1.3 kg/L.
Theoretical consumption: 0.12 kg/m² at 50 µm DFT (loss not included).
Drying time (25°C): surface dry 2 h; hard dry 24 h; full cure 7 d.
Application data (25°C)
Application methods: spray, brush, roller.
Pot life: 3 h.
Thinner: clean water, 5–15%.
Recoat interval: min 24 h.
Surface preparation
If exceeding maximum recoat interval, previous primer or intermediate coat must be roughened; when used as first primer, blast steel to Sa 2.5 or power-tool clean to St 3 with 30–75 µm profile.
System compatibility / packing / storage
Construction conditions: ambient 5–35°C; RH ≤85%; not suitable in rain, snow, strong wind, or heavy fog, or under intense summer sunlight.
Storage: dry, cool, ventilated; 5–35°C; avoid strong sunlight; no outdoor storage.
Shelf life: 6 months.
