KF-WF100 water-based fluorocarbon coating is the water-borne version of solvent-borne FEVE fluorocarbon coatings. Based on a water-based FEVE emulsion with VOC <80 g/L, it retains most of the weather resistance of fluorocarbon coatings (QUV-B 4,000-6,000 hours) while solving the high VOC emissions of solvent-borne products. It is a high-end topcoat solution in the context of green buildings and tightening environmental regulations. The weather resistance of the water-based product is currently slightly below that of solvent-borne, but it is sufficient for most application scenarios. Application performance is strongly affected by temperature and humidity and requires stricter application condition control.

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.
