Usage Instructions
1. Composition: ALITA 1506 resin does not contain wax, accelerator, or thixotropic agent.
2. Stability: To ensure the stability of SMC/BMC materials during storage, appropriate stabilizers should be added during production as needed.
Storage & Handling
- Protection: Resin contains harmful ingredients; wear necessary personal protective equipment to avoid skin and eye contact.
- Temperature: Strongly recommended to store in a stable environment below 25℃.
- Environment: Outdoor storage is strictly prohibited. Keep away from direct sunlight, steam pipes, or other heat sources to prevent moisture contamination and monomer loss.
- Management: Keep containers sealed and follow the "FIFO" principle for inventory turnover.
