PI-369: The Versatile Photoinitiator for UV Curing Applications
PI-369, also known as 2-Benzyl-2-(dimethylamino)-1-[4-(4-morpholinyl)phenyl]-1-butanone, is a highly effective photoinitiator used in various UV curing applications. It is a colorless to pale yellow liquid with a molecular weight of 357.5 g/mol and a melting point of -20°C.
Manufactured and supplied by INNO Specialty Chemicals from China, PI-369 is widely recognized for its excellent performance in initiating the photopolymerization of acrylates, vinyl ethers, and other unsaturated monomers under UV radiation. It is also compatible with various resins and coatings, including epoxy, polyester, acrylic, and polyurethane.
PI-369 is a versatile photoinitiator that offers several advantages over traditional initiators, such as benzoin ethers and benzophenone derivatives. It has a broad absorption spectrum in the UV range (250-420 nm), making it suitable for use with various UV lamps and LED sources. It also exhibits low volatility, high solubility, and excellent thermal stability, which ensures consistent and reliable performance in different curing conditions.
Moreover, PI-369 has a fast and efficient initiation rate, which enables rapid curing of coatings and inks. It also promotes high conversion rates and good film properties, such as hardness, adhesion, and chemical resistance. These features make PI-369 an ideal choice for demanding applications in the graphic arts, packaging, electronics, and automotive industries.
PI-369 is available in different grades and concentrations to meet specific customer requirements. It can be used as a single photoinitiator or in combination with other initiators, such as 4,4'-bis(diethylamino)benzophenone (DEAP) or 2-hydroxy-2-methyl-1-phenylpropan-1-one (HMPP). The optimal formulation and dosage of PI-369 depend on the substrate, the coating thickness, and the curing conditions.
As with any photoinitiator, PI-369 requires careful handling to ensure safety and efficacy. It is recommended to use protective equipment, such as gloves, goggles, and respirators, when handling the material. It should also be stored in a cool, dry, and well-ventilated area, away from heat sources and oxidizing agents.
In conclusion, PI-369 is a highly versatile and effective photoinitiator that offers numerous benefits for UV curing applications. Its broad absorption spectrum, low volatility, and fast initiation rate make it a preferred choice for various industries. INNO Specialty Chemicals is a reliable supplier of PI-369 and other specialty chemicals, providing customers with high-quality products and technical support.
