Product Description:
TPO is widely used as a photoinitiator in UV-curable coatings, inks, and adhesives due to its high efficiency in initiating polymerization under UV light. It is particularly valued for its ability to cure materials rapidly, even in thick layers or pigmented formulations, making it suitable for industrial applications. TPO is also employed in dental composites and 3D printing resins, where precise and fast curing is essential. Its compatibility with various monomers and oligomers enhances its versatility in formulating high-performance materials. Additionally, TPO's stability and low odor make it a preferred choice in applications requiring minimal environmental impact and user safety.
