Photoinitiators are highly sought after in numerous applications and end-use sectors, including adhesives, ink, and coating, among others, on account of their superior curability and resistance to a wide range of chemicals.

 In 2020, however, the demand for photoinitiators will have decreased due to the disruptions in the operations of numerous end-use industries caused by the global pandemic disease COVID-19.

 Adoption of automation, technological advancements, and rising demand for customized products all contribute to the expansion of the adhesives, coating, and paint industries. It is anticipated that this will increase the need for photoinitiators. Bio-printing is one application domain in which newly developed monomers/oligomers and photoinitiators are utilized in the development of novel use cases for 3D printing.

Hydrocarbons, alkenes, alkanes, nitrogenous hydrocarbons, polycyclic aromatic compounds, and oxygenated hydrocarbons are all classified as volatile organic compounds. On human bodies, a number of these compounds can induce direct or indirect harm. A multitude of compounds found in volatile organic compounds (VOCs) are water insoluble and therefore persist in water sources. In contrast to Volatile Organic Compounds (VOC), photoinitiators can be oligomerically dissolved in water, thereby permitting their application to have minimal or negligible environmental impacts.

Definition

A photoinitiator is a chemical compound that initiates or triggers a photopolymerization process when exposed to light, typically ultraviolet (UV) or visible light. In various industrial applications, especially in the field of coatings, adhesives, and printing, photoinitiators play a crucial role in initiating the curing or hardening of photo-sensitive materials. When illuminated, photoinitiators absorb light energy and undergo a photochemical reaction, generating reactive species such as free radicals or ions. These reactive species then facilitate the crosslinking or polymerization of monomers, creating a solid and durable material. Photoinitiators are essential components in photopolymer systems, providing a rapid and controlled means of curing that offers advantages such as quick processing times, improved efficiency, and reduced environmental impact compared to traditional curing methods.

Trend

Growing trend towards environmentally friendly and sustainable options

Additionally, photoinitiators find application in sectors such as dental product packaging, among others. It is anticipated that the expanding use of photoinitiators will continue to propel the global market for photoinitiators. In place of volatile organic compounds, photoinitiators may be utilized. These compounds are complex and difficult to degrade; if ingested directly, they can cause severe harm to the human body. Without appropriate disposal, these volatile organic compounds, which are insoluble in water, will remain suspended in water. As a result of the health and environmental risks associated with volatile organic compounds, manufacturers have begun to utilize photoinitiators.

In the presence of oligomers and monomers, photoinitiators become water-soluble, resulting in negligible to no environmental impact. It is also anticipated that the environmental advantages linked to the utilization of photoinitiators in the production of coatings, dyes, and adhesives will contribute positively to the worldwide photoinitiator market.

Although photoinitiators may not pose an environmental hazard in and of themselves, their synthesis necessitates the use of hazardous compounds that can be detrimental to human health. Because these chemicals are carcinogenic and can negatively affect reproductive health, their use has been prohibited or severely restricted in a number of European and North American nations. Regarding the management of these chemicals, a considerable number of APAC nations have considerably laxer regulations.

The increased cost of producing photoinitiators in North America and Europe as a result of the stricter regulations imposed on these chemicals has impeded the expansion of the market in those regions. As alternatives to volatile organic compounds, water-soluble photoinitiators are becoming increasingly in demand, particularly in the adhesives and coatings industry. Additionally, the sector is constrained by irregular light exposure, which may lead to manufacturing flaws in the final product. Inadequate illumination across the photoinitiators may impede the release of reactive species from certain photoinitiator molecules, thereby diminishing the coating or adhesive's overall efficacy due to its inability to generate a more intricate cross-linked polymer.
