Uniform thickness (0.5-2mm), good fluidity, easy to accurately weigh and feed, pH 14 (1% aqueous solution), avoid contact with amphoteric metals and organic compounds such as aluminum and zinc. Easy to absorb moisture and CO₂, requiring vacuum or inert gas packaging.
Store in a cool,dry,and well ventilated warehouse away from sources ofire and hea.The humidity inside the warehouse should not exceed 85%,and the packaging must be sealed to prevent moisture.It should be stored separately from flammable (combustible materials,acids,etc.,and avoid mixing storage. The storage area shall be equipped with suitable materials to contain leaked materials.
