Guideline Note:
1) The curing method adheres to GB/T 8237 standards. Curing system includes: 0.6% Co-Naph: 1.5%, AKZO M-50: 1.5%;
2) Post-curing process: Maintain at room temperature for 24 hours, then heat at 60ºC for 3 hours, followed by 110ºC for 2 hours.
4. Optimal Storage Conditions:
Store this premium resin in a cool, dry place below25 ºC. Ensure it is kept away from any sources of ignition or heat,and seal it tightly to shield from moisture, monomers, and volatile substances. Under these conditions, the resin maintains its integrity for up to 6 months.
