Before coating, remove all oil, grease, dust and other contaminants from the surface to be coated using suitable methods such as solvent cleaning and fresh water washing. * Steel: blast clean to Sa 2.5 or power tool clean to St 3.
Korepox Holding Primer EP1700, Korepox Prime EP6172, or according to specification.
Spraying: air or airless; brush and roller are recommended for small areas and stripe coats on specific edges and welds. Airless spray: nozzle tip 483~584 µm (0.019″~0.023″); nozzle pressure 26.4~43.8 MPa; fan width 40°~60°. * Due to its short pot life, twin-feed airless spray equipment is recommended.
Base : curing agent = 3 : 1 (by volume). Mix only in the ratio provided; do not alter or subdivide. Shake or stir the base thoroughly before mixing; pour the curing agent into the base with continuous mechanical stirring; do not mix in the reverse order; stir continuously until the mixture is free from lumps.
Not recommended.
The surface must be thoroughly clean and dry. Do not apply when the relative humidity exceeds 85%. The surface temperature must be at least 3 °C above the dew point to prevent condensation. The preferred temperature during application and curing is 10 °C to 49 °C.
Dry film thickness 300 µm. Different film thicknesses can be applied depending on the use and application area.
