Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide: A Powerful Photoinitiator for Polymerization
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, commonly known as TPO, is a highly efficient photoinitiator used in the polymer industry. It is a white crystalline powder that is soluble in organic solvents such as acetone, ethyl acetate, and toluene. TPO is widely used in various applications such as coatings, inks, adhesives, and composites. In this article, we will explore the properties and applications of TPO in detail.
Manufacturing and Supply
INNO Specialty Chemicals is a leading manufacturer and supplier of Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide in China. The company has a state-of-the-art manufacturing facility that meets international standards. INNO Specialty Chemicals produces high-quality TPO that is widely used in the polymer industry.
Properties
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide is a powerful photoinitiator that absorbs light in the UV region (around 365 nm) and undergoes a photochemical reaction to produce free radicals. These free radicals initiate the polymerization process in the presence of a suitable monomer or oligomer. TPO has a high molar extinction coefficient, which means that it can absorb light efficiently and initiate polymerization at low concentrations.
One of the key advantages of TPO is its ability to initiate polymerization in the presence of oxygen. This property is particularly useful in applications where oxygen inhibition is a concern. TPO is also thermally stable and does not decompose at high temperatures.
Applications
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide is a versatile photoinitiator that finds applications in various industries. Some of the key applications of TPO are:
Coatings: TPO is widely used in the formulation of UV-curable coatings for wood, metal, and plastic substrates. It provides excellent adhesion, chemical resistance, and weatherability to the coatings.
Inks: TPO is a popular photoinitiator in the formulation of UV-curable inks for printing on paper, plastic, and metal substrates. It provides fast curing, high gloss, and excellent print quality.
Adhesives: TPO is used in the formulation of UV-curable adhesives for bonding plastics, metals, and glass. It provides fast curing, high strength, and excellent adhesion to a wide range of substrates.
Composites: TPO is used in the manufacture of UV-curable composites such as fiber-reinforced plastics (FRP) and laminates. It provides fast curing, high strength, and excellent dimensional stability to the composites.
Conclusion
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide is a powerful photoinitiator that finds applications in various industries. It is a versatile and efficient initiator that provides fast curing, high strength, and excellent adhesion to a wide range of substrates.
