|No.||Test item name||Standard Requirements and Standard Terms Number||results of testing||in conclusion|
|1||The status in the container||After stirring, it is in a homogeneous liquid state or a thick fluid state without agglomeration.||After stirring, it became a homogeneous liquid without caking.||qualified|
|2||Drying time (dry)||≤12h||8h||qualified|
|3||Initial dry crack resistance||Allow 1 to 3 cracks, the width should be ≤ 0.5mm.||No crack||qualified|
|5||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|
|6||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|
|7||Fire resistance||When the coating thickness is not more than (5.0±0.5) mm, the fire resistance limit should not be less than 1.0h.
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 measured coating thickness was 4.7 mm, the fire resistance test was carried out until 160 min, and the fire endurance was equal to 2.7 h.||qualified|
