Photoinitiator 369: A Versatile Ingredient for UV-Curable Coatings and Inks

Photoinitiator 369, also known as PI-369, is a highly effective photoinitiator that is widely used in UV-curable coatings and inks. It is a clear to slightly yellow liquid with a molecular formula of C28H34N2O2 and a molecular weight of 442.59 g/mol. The chemical structure of PI-369 consists of a benzyl group, a dimethylamino group, and a morpholinyl phenylbutanone group, which makes it highly versatile and compatible with a wide range of resins and monomers.

PI-369 is a Type-1 photoinitiator, which means it absorbs UV light in the range of 320-400 nm and initiates a radical polymerization reaction. It has a broad absorption spectrum and can be activated by various sources of UV light, including medium-pressure mercury lamps, LED lamps, and sunlight. PI-369 is known for its fast curing speed, low odor, and low migration potential, which makes it an ideal choice for high-performance UV-curable coatings and inks.

One of the key advantages of PI-369 is its excellent compatibility with acrylate and methacrylate monomers, which are widely used in UV-curable formulations. It can be used in combination with other photoinitiators to achieve a synergistic effect and improve the curing efficiency and depth of cure. PI-369 is also compatible with various resins, including epoxy resins, polyester resins, and polyurethane resins, which makes it suitable for a wide range of applications.

PI-369 is commonly used in the formulation of UV-curable coatings and inks for various applications, including wood coatings, metal coatings, plastic coatings, and printing inks. It can be used in both clear and pigmented formulations and can provide excellent adhesion, chemical resistance, and scratch resistance. PI-369 is also used in the formulation of UV-curable adhesives, sealants, and encapsulants, where it can provide fast curing and high bond strength.
