|1||The status in the container||After stirring, it is in a uniform thick fluid state without agglomeration.||After stirring, it is in a uniform thick fluid state without agglomeration.||qualified|
|2||Drying time (dry)||≤24h||16h||qualified|
|3||Initial dry crack resistance||One to three cracks are allowed, and their width should be ≤1mm.||No crack||qualified|
|7||Water resistance||≥24h The coating should be free from layering, foaming and peeling.||Soaked for 24h, the coating did not rise, foam, fall off.||qualified|
|8||Cold and heat cycle resistance||≥ 15 times The coating should have no cracking, peeling or blistering.||After 15 cycles, the coating did not crack, peel off or blisters.||qualified|
|9||Fire resistance||When the thickness of the coating is not more than (25±2)mm, the fire resistance limit should not be less than 2.0h.
Fire resistance determination: Loss of carrying capacity -
The maximum deflection of the coated steel beam is L0/20 (L0 is the span of the steel beam in mm).
|The actual coating thickness is 23mm. The fire test was carried out until 180 minutes
Fire resistance is equal to 3.0h.
