Precautions 1. The flame retardant glass flake coating shall be stored in a dry, ventilated and cool place, and it is strictly prohibited to be exposed to rain, sun and fire. 2. The mixing of accelerator and curing agent may cause explosion hazard. Note that the accelerator and curing agent shall be stored separately. It is strictly prohibited to mix the accelerator and curing agent directly. 3. The storage period of flame retardant glass flake coating is 3 months in summer and 6 months in winter. If the products beyond the storage period do not agglomerate, they can continue to be used after the technical indicators pass the inspection.
