Product Introduction:
Photoinitiator TPO (full chemical name: Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) is a common UV initiator, widely used in UV curing systems.
Photoinitiator TPO is a typical photoinitiator. It can absorb light energy of a specific wavelength under UV light and quickly decompose and release free radicals, thereby initiating the cross-linking reaction of monomers or polymers. TPO is usually white or light yellow crystals, has good solubility, is not easy to volatilize, and can effectively promote the photocuring reaction.
The structural characteristics of Photoinitiator TPO give it good light absorption ability. Its molecular structure contains a phosphate group and a phenyl ring, which can effectively absorb long-wave ultraviolet rays (UV-A). The excitation spectrum of TPO is usually concentrated in the wavelength range of 360-380nm, which enables it to be fully excited under UV light sources and produce a large number of free radicals.
Therefore, Photoinitiator TPO is suitable for UV curing systems that require lower energy. Compared with other photoinitiators, TPO can initiate polymerization reactions more quickly and efficiently under the same UV light irradiation conditions.
One of the advantages of Photoinitiator TPO is its efficient initiation performance. Compared with traditional photoinitiators, TPO reacts faster under UV light and can effectively reduce the curing time.
In addition, TPO has low yellowing, and the light-cured materials usually show good optical properties, which is suitable for the production of transparent coatings and high-gloss products. This feature makes TPO widely used in industries such as coatings, inks and adhesives with high requirements.
Another significant advantage is the low toxicity and high safety of Photoinitiator TPO. Compared with some traditional photoinitiators, the reaction products of TPO usually do not produce toxic or irritating gases, which makes it have great advantages in environmental protection and safety.
In practical applications, Photoinitiator TPO also shows good stability and can maintain activity for a long time in high temperature, humidity and other environments. Therefore, TPO is considered to be a very ideal initiator in the photocuring industry.

Photoinitiator TPO (Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) is an efficient and multifunctional photocurable material. Its unique chemical structure and photosensitivity make it play an important role in many fields. The following is a detailed introduction to its application in various fields.
Coating field
In the coatings industry, Photoinitiator TPO is favored for its efficient light-curing properties. It can quickly absorb ultraviolet light energy, trigger the rapid polymerization of resins and monomers in the coating, and achieve rapid curing of the coating. This fast-curing feature not only improves production efficiency, but also helps reduce energy consumption and volatile organic compound (VOC) emissions.
It is suitable for use on a variety of substrates, including paper, wood, metal, plastic and glass, making it widely used in coatings in the furniture, automotive, electronics and construction industries.
printing ink
The application of Photoinitiator TPO in printing inks is also significant. It ensures that the ink solidifies quickly under UV light, improving printing speed and quality. This feature is particularly important for applications that require fast production and high print quality, such as packaging printing, label printing and commercial printing. Its use also helps reduce ink odor and improves the comfort of the work environment.
Adhesive
In the adhesive industry, Photoinitiator TPO is used to produce UV-curable adhesives that cure rapidly when exposed to UV light, providing instant bond strength. This rapid curing property is very important for improving production efficiency and reducing production costs. UV-curable adhesives are widely used in the electronics, medical, automotive and construction industries to bond a variety of materials such as plastics, metals and glass.
Optical fiber coating
The application of Photoinitiator TPO in optical fiber coatings is also an important area. Optical fiber coatings need to have excellent chemical and weather resistance to protect the fiber from the outside environment. It provides this protection while ensuring fast curing and good optical properties of the coating.
composite materials
In the field of composite materials, the application of Photoinitiator TPO brings new possibilities for material performance improvement and application expansion. It can efficiently absorb light of specific wavelengths and convert it into chemical energy, thereby triggering chemical reactions in composite materials and achieving curing and modification of materials. This characteristic gives it a unique advantage in the preparation of composite materials, which can improve the curing speed of the material, enhance the mechanical properties and weather resistance of the material.
tooth fillings
In the dental field, Photoinitiator TPO is used in tooth fillings, providing an efficient, safe and aesthetically pleasing tooth restoration solution. It can respond quickly to ultraviolet or visible light, promoting the rapid polymerization of resin monomers to form a hard and durable restoration. Its use not only shortens the treatment time, but also significantly improves the repair effect, and its photolysis products show good biocompatibility, ensuring the safety of use in the oral environment.
photoresist
In the field of photoresist, Photoinitiator TPO has become the industry leader with its excellent performance. It has efficient light absorption capabilities and can quickly initiate polymerization reactions in a short time, thereby increasing the curing speed of the photoresist. This feature makes it popular in modern industries that pursue efficient production.
Photopolymerizing printing plates and stereolithographic resins
Photoinitiator TPO provides fast curing and high-resolution printing results in applications such as photopolymerizing printing plates and stereolithographic resins. This is crucial to improve printing quality and efficiency, especially in the fields of fine printing and three-dimensional printing.
To sum up, Photoinitiator TPO plays an important role in many fields because of its unique properties. With the continuous development of light curing technology, its application prospects will be broader, bringing higher efficiency and better performance to all walks of life.
Photoinitiator TPO (Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) is considered a relatively safe chemical in its applications, but proper safe handling practices still need to be followed, especially when used in industrial and experimental environments . The safety of TPO is mainly affected by its toxicity, irritation, environmental impact and other factors
1. Toxicity
Photoinitiator TPO itself has low toxicity. According to existing research and information, TPO will not cause significant harm to the human body under appropriate conditions of use. It is not absorbed through the skin or respiratory tract under normal conditions of use and is therefore less irritating to the skin and respiratory system.
However, in higher concentrations or when used improperly, Photoinitiator TPO may cause some irritation to the skin and eyes. Therefore, it is recommended to wear appropriate protective equipment such as gloves, goggles, and protective clothing when handling TPO to avoid direct contact with skin and eyes.
2. Sensitization
Photoinitiator TPO may cause mild allergic reactions in some cases, especially in people with a pre-existing chemical allergy. Although TPO itself has low allergenicity, it may still cause allergic symptoms, such as skin redness, swelling, itching, etc., in the case of long-term and large-dose exposure. Therefore, it is recommended to take protective measures during operation to avoid long-term contact or high-concentration exposure.
3. Volatility and gas release
Photoinitiator TPO has low volatility, is relatively stable at room temperature, and does not easily emit harmful gases. Therefore, the use of TPO usually does not produce the release of harmful gases, especially during ultraviolet irradiation, and the reaction products are generally non-toxic.
Compared with some traditional photoinitiators, Photoinitiator TPO is less likely to produce harmful substances, such as chlorides, alcohols and other volatile organic compounds (VOCs) during the photocuring process. This gives TPO certain advantages in terms of environmental protection and health.
