Note 1: In the actual lamination process, the crosslinking degree reaches the design value and the component yield is high as a guide, which is adjusted according to the actual working condition onsite.
Note 2: It is recommended to use it up within 48 hours after opening of the original packing.
Note 3: These are typical laboratory values that may change depending on the cure conditions as well as the test conditions and methods.
