Note: 1. The preparation method is in accordance with GB / T8237-2005，Curing system: Accelerator RCA 1.0%, curing agent Butanox M-50 1.0%.
|
|
2. Casting body post-treatment: room temperature×24 hours + 60 ℃×3 hours + 120 ℃×1 hours.

|
|
Matters needing attention:
|
|
1. When the construction environment is high and the gel time is too short, the dosage of curing agent can not be reduced, and the polymerization inhibitor should be added as needed. When the surface is sticky, wax fluid should be added properly.
|
|
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.
