Note£º

1.The above-mentioned test adopt 0.8mm thick rust removal , degrease cold-rolled stencil plate , and the scribble membrane thickness is 50-70 microns;
2.The index of performance applied membrane above may be slightly reduced with reducing of the gloss.

7.Average Coverage Rate
9-12 square per kg, membrane thick is 60 (calculated as the 100% usage rate)
8.Packing
Carton packaging, with polyethylene chloride bag, the net weight is 20 kg.
9.Storage
The products must be stored in dry room with good ventilation ,with temperature lower than 30 and should avoid direct sunlight. prohibit to piling up in the open.
