Matters needing attention:
|
|
1. When the construction environment temperature is high and gel time is short, the dosage of curing agent can not be reduced, and gel retarding agent RS-104 should be added as needed.
|
|
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.
