Detailed Product Description

 

Feature:

  1. Very good adhesion with the substrate.
  2. Coating with excellent cathodic disbonding resistance and high electrical insulation
  3. Coating density, continuous, brightness, resistance to penetration, less funnelled
  4. Coating with high bond strength of concrete, strong bond stress.
  5. Good toughness, no cracking for bending
  6.  Low melting temperature, high reactivity, high curing completion rate, good mechanical propertie
  7. Versatility, low powder consumption
  8. Steel wire drawing in the powder coating can be reduced or avoided

Carried Standard: JG 3042-1997; GB/T 25826-2010

Application Area: Can be widely used in Bridges, ports, airports, buildings, basements, high-speed rail, etc.

Applicable process: Electrostatic Coating

Notes:

1. Steel surface scale remove clean, reveal metal color; Steel surface roughness handling quality standard, appropriate for 50-70 - mm; Derusting grade level Sa2 1/2 (GB/T8923, no chloride attached on steel surface. Preheating: temperature should be controlled in 220-245 ℃.)

2. Product should be stored in ventilated, dry, indoor temperature below 27 ℃, away from heat, corrosive chemicals and chemical solvents, avoid bright light, the maximum stack height should not exceed 4 layers, avoid prolonged pressure, ensure airtight box. In case the clot and damp affects the fluidization performance.

3. As the product has high reactivity, it is recommended that storage period for 27 ℃ under 3 months for the best. Exceed shelf life, should be test its performance first.
