Typical Properties

Usage

UV/LED-curable inks and coatings: Printing inks for screen printing, offset printing, flexographic printing, and inkjet inks achieve ultra-fast curing, improving printing efficiency and abrasion resistance. Paints and varnishes for wood coatings, plastic coatings, metal coatings, and varnishes provide a hard, scratch-resistant surface.

Low-yellowing and White System Curing: Compared to traditional photoinitiators, TPO-L exhibits low yellowing, making it suitable for curing white paints and varnishes with strict color requirements.

Deep-layer Curing and Thick-film Applications: TPO-L has a long-wave UV absorption band (approximately 370nm), allowing it to penetrate coatings containing pigments (such as titanium dioxide) or thick ink layers, achieving uniform, deep-layer curing.
