NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of chemical solutions, and we are pleased to highlight the exceptional properties of 2-Hydroxy-2-methylpropiophenone (CAS:7473-98-5) as a non-yellowing photoinitiator.

In many UV-curable applications, maintaining the original color of the substrate and the cured material is critically important. Traditional photoinitiators can sometimes lead to yellowing, especially after exposure to UV light or over time, which can be detrimental to the final product’s appearance. 2-Hydroxy-2-methylpropiophenone, however, stands out for its remarkably low tendency to cause yellowing. This makes it an ideal choice for applications where color fidelity is paramount, such as clear coatings, white inks, and light-colored plastics.

The excellent color stability of this compound ensures that products cured with it retain their clarity and original hue, providing a significant aesthetic advantage. This property is particularly valued in industries like automotive coatings, high-end packaging, and consumer electronics, where visual appeal is a key selling point. As a result, it is often recommended as a preferred photoinitiator for inks and coatings that demand superior visual performance.

Beyond its non-yellowing attribute, 2-Hydroxy-2-methylpropiophenone is a highly efficient initiator, contributing to fast curing speeds. This dual benefit of excellent color stability and high reactivity makes it a versatile and valuable component in many UV-curable systems. Its ability to be easily compounded with other photoinitiators further enhances its utility, allowing formulators to fine-tune performance characteristics.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing chemical intermediates that meet the highest standards of quality and performance. By choosing our 2-Hydroxy-2-methylpropiophenone, you can ensure your products benefit from exceptional UV curing efficiency and outstanding resistance to yellowing.
