Matters needing attention:
|
|
1. Due to the high temperature in summer, please add proper amount of polymerization inhibitor to ensure the storage stability of SMC / BMC.
|
|
2. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months.
