Coverage
7- 9 square meters per kg with coat thickness 90 μm(calculated as the 100% usage rate).
Packing
Carton packaging, with polyethylene chloride bag, the net weight is 25kg.
Storage
The products must be stored in dry room with good ventilation ,with tempe-
rature lower than 35ºC and should avoid direct sunlight. Prohibit to piling up in the open. Under this condition, the powder can be steadily maintained for one year, expired products still can be used provided testing results meet the utilizations standards.
