In order to achieve the ideal performance, the coating should have a series of properties, mainly including physical and chemical properties, operation process performance and working performance:

(1) Physical and chemical properties: including color, fineness, density or Baume degree, viscosity, suspension, solid content, thermal conductivity, pH value, chemical composition, etc.
(2) Operation process performance: including brushing property, sagging property, leveling property, rheological property, permeability, wettability, ignition and combustion property, etc.
(3) Working performance: coating surface strength (surface abrasion resistance), adhesion strength, coating thickness, drying crack resistance, rapid heat crack resistance, air permeability, gassing resistance, sand sticking resistance, peeling resistance, etc.
