🔬 Key Application Insights

3D Printing (especially in dentistry):
This represents a critical application for TPO-L in recent years. Studies indicate that resins using TPO-L demonstrate superior biocompatibility (lower cytotoxicity) and color stability compared to some traditional photoinitiators. This is crucial for dental restorations requiring long-term placement in the oral cavity, such as crowns and models.

Coatings and Inks:
TPO-L enables efficient deep-cure and surface-cure properties. Its low yellowing characteristics help preserve the original color of coatings or printed materials, particularly in pigmented systems (especially white and colored inks).

Adhesives and Composites:
TPO-L’s liquid state facilitates easy mixing in formulations. Studies also confirm its ability to achieve efficient curing in adhesive formulations like pressure-sensitive adhesives.
