Epoxy ester primer factory wholesale, Waterborne Acrylic Polyurethane, Steel structure equipment paint, Magnetic paint, Engineering machinery paint. Basic Properties: Composition: Epoxy ester primer consists of epoxy ester resin, filler, rust inhibitor, flame retardant, drying agent, organic solvent, etc. Color: Common colors include iron red, zinc yellow, etc. Physical Properties: The paint film is tough and durable, with good adhesion, water resistance, and rust prevention. Technical Performance: Moisture and salt mist resistance is better than alkyd primer. Epoxy ester primer also has good rust prevention, flexibility, and impact resistance. Application Range: Epoxy ester primer is widely used as a rust preventive primer for metal materials and mechanical surfaces, especially suitable for steel structures, metal equipment, pipelines, and anti-corrosion coating for mechanical products. In addition, zinc acrylic epoxy ester primer is mainly used for the coating of aluminum and light metal substrates. Technical Parameters: Viscosity: Typically 50 (measured by the No. 4 cup). Fineness: Zinc yellow epoxy ester primer ≤50μm, iron red epoxy ester primer ≤60μm (another specification is ≤60mm, the specific requirement should be determined according to the product standard). Drying Time: Surface dry (25℃) ≤2 hours, fully dry (25℃) ≤24 hours. Adhesion: ≤2. Hardness: ≥0.4. Salt Resistance: No bubbles, no rust after immersion in 3% NaCl solution at 25℃ for 48 hours.
