Note:
1) The casting is made according to GB/T8237; Curing System: Accelerator 0.6% Co-Naph: 2.0% ; Hardener AKZO M-50: 2%;
- Post curing: RT×24hrs+60ºC×3hrs+110ºC×2hrs
- Storage & Transportation:
- Avoid exposure to heat sources such as direct sunlight or steam pipes. Stored in a dry place at temperatures below 25ºC and the shelf life is 6 months. Keep sealed to prevent moisture pick-up and monomer loss.
- Transportation should fit the State Council "Chemistry Dangerous Articles Safety Management Regulations". Because it contains styrene monomer, it is hazardous and inflammable.
