Case Study：SGP Laminated Glass Fogging Defects of Consistent Shape
2026-06-18
Have you ever seen such unusual glass fogging? Each pane of glass exhibits fog-like defects in exactly the same position and with highly consistent shapes.
During troubleshooting, the customer polished the glass surface to rule out surface-related factors, ultimately confirming that the root cause lay inside the glass itself.
Faced with this batch of glass requiring reprocessing and tight delivery deadlines, the Innolamin Technical Team rushed to the site promptly to conduct technical diagnostics and process optimization.
Through professional analysis, it was determined that the regular fogging defects in SGP laminated glass are closely related to autoclave processing parameters and on-site operating procedures.
Key influencing factors include processing temperature, holding time, cooling rate, loading capacity, and loading method.
Instead of carrying out blind rework, the technical team precisely adjusted the autoclave process parameters and performed refined reprocessing on the defective glass.
In the end, the product quality fully met standards, successfully fulfilling the requirements.
Innolamin Technical Recommendations
To effectively prevent internal fogging defects in SGP laminated glass, two critical points are recommended during production and processing:
- When loading glass, leave sufficient gaps to ensure smooth air circulation inside the autoclave.
- Strictly control the cooling rate to no less than 3.3°C per minute.
More than interlayers, Innolamin always takes technology as its core, focusing on solving various difficult problems in glass deep processing.
