Note: 1) Pouring method is according to GB/T8237-2005. Curing system: HS-909: 1.5%, AKZO M-50: 1.5%;
2) The curing system after casting is: room temperature (24 h) + 60°C (3 h) + 110°C (2 h).
n Caution:
The product should be stored in a cool place under 25°C, away from fire, isolated from heat sources (e.g. direct sunlight or steam, etc.), and the drum should be kept sealed to prevent moisture intrusion and volatilisation of the monomers. the shelf-life of the product under 25°C is three months.
