1. Q: How do you ensure consistent quality?
A: Full-process quality control from raw material to finished product.
2. Q: Is each batch tested?
A: Yes, full inspection before delivery with COA provided.
3. Q: What quality system is certified?
A: ISO 9001 quality management system.
4. Q: Will it gel during storage?
A: No, under recommended storage conditions it stays stable for 12+ months.
5. Q: Will it delaminate or precipitate?
A: Charge stabilization technology prevents sedimentation and delamination.
6. Q: Does pH change during storage?
A: It remains stable within the specified range.
7. Q: What happens if it freezes?
A: Freezing may damage colloidal structure; avoid freezing.
8. Q: Does sunlight affect it?
A: Long-term direct sunlight is not recommended; store in shade.
9. Q: Will it grow mold?
A: Fully inorganic formula, no mold growth.
10. Q: Is there batch-to-batch viscosity variation?
A: Variation is strictly controlled within a narrow range.
11. Q: Do you provide third-party test reports?
A: Yes, SGS/BV/TUV test reports are available.
12. Q: Can customers arrange factory inspection?
A: Yes, factory audits are welcome by appointment.
13. Q: Does it meet REACH/RoHS?
A: Yes, compliant with REACH and RoHS standards.
14. Q: Is there a return policy for quality issues?
A: Quality issues are handled per formal quality agreement.
15. Q: How to judge if it has expired?
A: Obvious gelation, delamination or sharp viscosity rise means expiration.
16. Q: Does purity affect optical performance?
A: Yes, higher purity means better clarity and anti-yellowing.
17. Q: Why is narrow particle size distribution important?
A: It ensures uniform curing and consistent optical quality.
18. Q: Is the product traceable?
A: Yes, each batch has a unique number for full traceability.
19. Q: Do you offer stability test data?
A: Yes, accelerated aging and long-term storage data are available.
20. Q: Is the formula fixed?
A: Standard grades are fixed; custom grades can be adjusted.
