Usage Instructions
1. Composition: ALITA P10-901 resin contains wax and is pre-accelerated, but does not contain thixotropic agent.
2. Processing: During production, cutting and polishing must only be performed after the resin is fully cured.
3. Post-Curing: For optimal product performance, post-curing at 60-70℃ for at least 3 hours is recommended.
4. Filler Management: Fillers should be protected from moisture absorption. High moisture content will affect product curing and lead to reduced performance.
Storage & Handling
- Safety Protection: This resin contains components that may be harmful if mishandled. Avoid contact with skin and eyes, and necessary protective equipment and clothing must be worn during operation.
- Storage Temperature: It is strongly recommended to store all materials in a stable temperature environment below 25℃ (77℉). Keep away from direct sunlight or heat sources like steam pipes.
- Environmental Requirements: To prevent moisture contamination, do not store outdoors. Keep sealed to prevent moisture absorption and monomer loss.
- Inventory Rotation: Follow the "First-In, First-Out" principle.
