CAS 84434-11-7 Photoinitiator For UV-Curable And And Inks Ethyl (2,4,6-Trimethylbenzoyl) Phenylphosphinate TPO

 

Product Description

Ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate is an organic compound with the chemical formula C20H21O3P. It is commonly known as TPO (2,4,6-trimethylbenzoylphenylphosphinate).

 

Description:

• Chemical Formula: C20H21O3P
• Molecular Weight: Approximately 338.36 g/mol
• Appearance: Ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate typically appears as oily liquid.
• Solubility: It is soluble in organic solvents like ethanol.

 

Features:

• Photoinitiator: Ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate is primarily known as a photoinitiator. It absorbs UV light and undergoes a photochemical reaction, generating free radicals that initiate polymerization or crosslinking of certain materials.
• Efficient Absorption: TPO exhibits efficient absorption of UV light in the range of 250-400 nm, making it suitable for UV curing applications.
• Low Yellowing: TPO is known for its low yellowing tendency, enabling it to maintain the clarity and color stability of UV-cured coatings and formulations.
• Compatibility: It is compatible with various monomers, oligomers, and resins commonly used in UV-curable systems.

Applications:

• UV-Curable Coatings: TPO is extensively used as a photoinitiator in UV-curable coatings and inks. It initiates the crosslinking and polymerization reactions when exposed to UV light, resulting in the rapid curing of the coating.
• Adhesives and Sealants: It finds application in UV-curable adhesives and sealants, enabling fast and efficient bonding of substrates.
• 3D Printing: TPO is employed in UV-curable resins used for 3D printing processes, providing rapid and precise curing of printed objects layer by layer.
• Dental Materials: Due to its low yellowing and high reactivity, TPO is utilized in dental materials such as dental adhesives, composites, and coatings.
• Electronics: It can be used in the manufacturing of electronic devices such as circuit boards, optical films, and protective coatings, where fast curing and low yellowing properties are important.
