PI-369: A Versatile Photoinitiator for High-Quality UV-Curable Coatings

UV-curable coatings have become increasingly popular due to their superior performance and environmental benefits. They offer excellent adhesion, durability, and fast curing times, which make them ideal for various applications, including automotive, electronics, and packaging. However, the success of UV-curable coatings relies heavily on the choice of photoinitiator, which initiates the crosslinking process when exposed to UV light. One of the most versatile photoinitiators available in the market is PI-369, also known as 2-Benzyl-2-(dimethylamino)-1-[4-(4-morpholinyl)phenyl]-1-butanone.

PI-369 is a highly efficient Type I photoinitiator that absorbs UV light in the range of 320-400 nm, which is ideal for most UV-curable coatings. It generates free radicals upon irradiation, which initiate the polymerization process by reacting with unsaturated monomers or oligomers. PI-369 has several advantages over other photoinitiators, including:

- Fast curing: PI-369 has a high initiation rate, which means it can initiate polymerization quickly and efficiently, leading to fast curing times.

- Low volatility: PI-369 has a low vapor pressure, which minimizes the risk of air pollution and worker exposure.

- High solubility: PI-369 is highly soluble in common solvents used in coatings, such as acetone, ethyl acetate, and isopropanol, which makes it easy to formulate.

- Good compatibility: PI-369 is compatible with various monomers and oligomers, including acrylates, methacrylates, epoxies, and vinyl esters, which makes it versatile.

- Low yellowing: PI-369 has a low tendency to yellow over time, which is essential for coatings that require color stability.

PI-369 is manufactured and supplied by INNO Specialty Chemicals, a leading Chinese company that specializes in UV-curable coatings and photoinitiators. INNO has a strong R&D team that continuously develops new products and formulations to meet customer needs. PI-369 is one of their flagship products and has been widely used in various coatings applications, such as wood, metal, plastic, and paper.

In conclusion, PI-369 is a versatile photoinitiator that offers many advantages for UV-curable coatings. Its fast curing, low volatility, high solubility, good compatibility, and low yellowing make it an excellent choice for various applications. INNO Specialty Chemicals is a reliable supplier of PI-369 and other photoinitiators, and they have a strong commitment to quality and innovation. Choosing the right photoinitiator is crucial for the success of UV-curable coatings, and PI-369 is undoubtedly one of the best options available in the market.
