Application
Photoinitiators are compounds that initiate or promote the photopolymerization process when exposed to light. They are widely used in various industries and applications. Here are some common applications of photoinitiators:
01. UV Curing
Photoinitiators initiate the rapid curing of UV-curable resins, inks, coatings, adhesives, and varnishes upon exposure to UV light.
02. 3D Printing
Photoinitiators enable the layer-by-layer solidification of UV-curable resins in stereolithography and digital light processing 3D printers.
03. Wood Coatings
Photoinitiators facilitate the quick curing of UV-curable coatings, providing high gloss and chemical resistance in wood finishing.
04. Graphic Arts
Photoinitiators are essential in UV-curable inks for fast curing, durable prints in flexography, screen printing, and digital printing.
05. Electronics
UV-curable adhesives, coatings, and encapsulants with photoinitiators enhance bonding and protection in electronics assembly.
06. Dental Materials
Photoinitiators enable efficient curing of UV-curable dental composites, adhesives, and sealants, aiding in dental restorations.
It’s important to note that different photoinitiators may have specific applications and compatibility requirements. The selection of the appropriate photoinitiator depends on factors such as the resin system, light source, curing speed, and desired properties of the cured material. Consultation with us to ensure optimal results for your specific application.

Photoinitiator FAQ
What is a photoinitiator?
A photoinitiator is a chemical compound that initiates a chemical reaction, typically polymerization, when exposed to light. It absorbs the energy from the light and transfers it to a reactive species, which then starts the desired reaction.
What are photoinitiators used for?
Photoinitiators are primarily used in UV curing processes. UV curing is a technique in which a photopolymerizable material, such as a coating, adhesive, or ink, is exposed to UV light, and the photoinitiator initiates the curing or hardening process. Photoinitiators are also used in other applications, such as 3D printing, lithography, and dental materials.
What are the different types of photoinitiators?
There are several types of photoinitiators, including:
- Free Radical Photoinitiators: These generate free radicals upon light exposure, which initiate polymerization reactions. Examples include benzoin, benzoin methyl ether, and benzoin ethyl ether.
- Cationic Photoinitiators: These generate cations (positively charged species) upon light exposure, which initiate polymerization reactions. Examples include diaryliodonium salts and triarylsulfonium salts.
- Type I Photoinitiators: These directly undergo photolysis or decomposition upon light exposure, generating reactive species. Examples include benzoin and benzoin methyl ether.
- Type II Photoinitiators: These absorb light energy and transfer it to a co-initiator or a monomer, which then generates reactive species. Examples include benzoin ethers and benzophenone derivatives.
Are there any safety considerations when working with photoinitiators?
Yes, it’s important to follow appropriate safety precautions when handling photoinitiators. Some photoinitiators may be toxic, irritants, or sensitisers. It is recommended to use personal protective equipment (PPE) such as gloves, goggles, and lab coats when working with photoinitiators. Additionally, proper ventilation should be maintained in the work area.
Can I mix different photoinitiators?
Yes, it is possible to mix different photoinitiators to achieve desired curing characteristics or to fine-tune the curing process. However, it is important to consider the compatibility and reactivity of the photoinitiators and ensure that they do not adversely affect each other’s performance.
Can I get custom formulations from a photoinitiator manufacturer?
Yes, WPA offer custom formulation services. We can work with you to develop and produce photoinitiators tailored to your specific requirements, such as specific reactivity, absorption spectra, or compatibility with certain materials.
