The above properties performance may decrease slightly with the reduction of luster.
VIII. Packing:To be packed with cartons, with polyvinyl chloride bags. The net weight of each box is 20kg.
IX. Storage:The products must be stored in a dry room with good ventilation, with temperature lower than 35℃ and should avoid direct sunlight. Provided that the powder coatings are stored in a room with air-condition, then before using, they should be re-stored under room temperature or the same temperature with the spraying equipments so as to avoid dampening. Under this condition, powder coatings could be maintained for 12 months. Expired products still can be used provided testing results meet the utilization standards.
Remark: For the powder of low temperature solidification and luster is lower than 40% (60°), the storage temperature is better lower than 30℃.
X. Health and safety:There are no hazardous ingredients in all the raw materials of powder coatings and no hazardous gas will be released while using. However, the inhalation of dusts should be avoided. An operator should wear an anti-dust mask and try best to avoid long-time contact with powder coatings.
