Photoinitiator PowerCure TPO: Innovation Drives Sustainable Development in the Coatings and Ink Industry

In today's highly information-based society, the photoinitiator PowerCure TPO, as an efficient and environmentally friendly free radical photoinitiator, is gradually becoming a key component of the coating and ink industry. This photoinitiator, which has the characteristics of fast curing, yellowing resistance, and low odor, has injected new impetus into the sustainable development of the industry.

The photoinitiator PowerCure TPO, a benzophenone derivative, has strong light-absorbing ability and can quickly initiate polymerization under ultraviolet light irradiation. This characteristic allows TPO to play an important role in the production of UV curing coatings and inks, which can achieve rapid and deep curing and improve production efficiency.

Another important property of PowerCure TPO is its resistance to yellowing. Under light conditions, general paints and inks are prone to color changes, which affects the appearance and use effect. However, TPO can effectively inhibit the occurrence of yellowing during the photopolymerization process and ensure product color stability. This feature undoubtedly improves the quality and service life of coatings and inks that need to be exposed to light for a long time.

Low odor is another outstanding feature of PowerCure TPO. During the production process, coatings and inks will emit pungent odors, which not only affects the health of employees and surrounding residents, but also causes pollution to the environment. Using TPO as a photoinitiator can effectively reduce odor emissions and achieve green production.

PowerCure TPO has a wide range of applications, including but not limited to UV curable coatings and inks on substrates such as paper, wood, metal, plastic and glass. As a standalone initiator, PowerCure TPO can be used in combination with other photoinitiators such as alpha-hydroxyketone, such as PowerCure 4265 (50% PowerCure TPO and 50% PowerCure 1173) to achieve even better performance. The recommended addition level is 0.3-3% by weight of the formula.

As environmental regulations become increasingly stringent and consumers' demand for green products increases, photoinitiator TPO is gradually becoming the first choice in the coating and ink industry due to its high efficiency and environmentally friendly properties. Looking to the future, with the advancement of technology and the growth of market demand, the application prospects of TPO will be broader.
