Water-based Photocuring Technology: The Application and Advantages of High-performance Photoinitiators 819DW and 2959

Abstract

With the increasing strictness of environmental protection regulations and the rapid development of green chemistry, water-based UV-curable materials are gradually replacing traditional solvent-based systems and becoming a new trend in the industry. This article focuses on two water-based photoinitiators 819DW and 2959, analyzes their performance characteristics and excellent performance in the field of water-based UV, and provides a reference for the application of green chemical materials.

With the growing strictness of global environmental protection regulations and the development of green chemistry, traditional solvent-based UV-curable materials are gradually being replaced by water-based systems. Water-based photocurable products are composed of water-based oligomers and water-based photoinitiators. It requires that water-based photoinitiators have good compatibility with water-based oligomers, high photoactivity in an aqueous medium, high initiation efficiency, as well as low volatility, being non-toxic, colorless, and odorless.

Water-based photoinitiators can be divided into two categories: water-dispersible type and water-soluble type. Many water-based photoinitiators are modified by introducing anionic, cationic, or hydrophilic non-ionic groups into the structure of the original oil-soluble photoinitiators to make them water-soluble.

Today, we will focus on introducing two photoinitiator products that perform outstandingly in the field of water-based UV: photoinitiator 819DW and photoinitiator 2959.

Their main performance characteristics are shown in the following table:

Water-based photocuring technology, with its characteristics of environmental protection and high efficiency, has become the mainstream direction for future development. The excellent performance of photoinitiators 819DW and 2959 provides important support for this field.
