    storage and use


    ① Shelf life: Under normal temperature conditions, 3 months from the date of shipment; it is recommended that the storage temperature should be below 25 ℃, and the shelf life of the product will decrease with the increase of the storage environment temperature
    .
    Avoid being near or exposed to heat sources, such as direct sunlight, near steam pipes, etc.


    ②When using, the accelerator should be added first, and then the curing agent should be added after complete mixing
    .
    Avoid storing hardeners in metal containers


    ③ For safety measures, please refer to the product safety data sheet (MSDS)
