KF-GF100 epoxy glass-flake coating replaces MIO as the main anti-corrosive pigment with micron-scale glass flakes (Glass Flake, thickness about 5 micrometers, particle size 50-500 micrometers). The glass flakes form a barrier of dozens of overlapping layers within the coating, giving permeation resistance 10-50 times higher than conventional epoxy coatings. A dry film thickness of 200-500 micrometers can be achieved in a single application without sagging. It is especially suitable for immersion service (tank interiors, sewage pools, ship hulls below the waterline) and severe chemical-corrosion environments. Excellent resistance to seawater, acids, alkalis and salt solutions.

4. Application Guide
Surface preparation
Thoroughly clean the substrate surface to remove oil and rust. Abrasive-blast steel to Sa2.5 (ISO 8501-1) with 40-75μm surface profile. Concrete substrate moisture content must be below 6%, grind to remove laitance. For old coatings, remove loose areas and roughen the surface.
Mixing / compounding
According to the mix ratio indicated on the product label, add the hardener (component B) slowly to the base (component A) and mechanically stir for 3-5 minutes until uniform. Let stand to mature for 10-15 minutes before use. Use up within the specified pot life after mixing.
Application method
Recommended air spray (gun orifice 1.5-2.0 mm, pressure 0.4-0.6 MPa) or airless spray (nozzle 0.38-0.53 mm, pressure 15-25 MPa). Small areas may be brushed or rolled. Keep each coat dry film thickness within the specified range.
Curing conditions
Self-cures at ambient temperature (23°C) provided relative humidity meets requirements. Do not apply under low temperature (<5°C) or high humidity (>85%). Conduct performance testing only after full cure.
