Notes:
1. Casting follows GB/T 8237-2005. System: ALITA BPO-50F 1.5%.
2. Post-curing: RT 24h + 60℃ 3h + 100℃ 2h.
Usage Instructions
1. Selection: Users should choose the appropriate resin based on specific environmental conditions and process requirements.
2. Stirring: As 1102H is thixotropic, some settling may occur. Stir gently before use to re-disperse evenly.
3. Safety: Avoid skin/eye contact. Use protective equipment.
Storage & Handling
- Conditions: Store below 25℃ in a cool place. Away from fire and heat (direct sunlight/steam pipes).
- Sealing: Keep drums sealed to prevent moisture ingress and monomer (styrene) loss.
- Shelf Life: 3 months under 25℃. Follow "FIFO" principle.
