Product Description：

Properties and Usage:

Photoinitiator EHA, also known as synergist EHA, is an efficient UV absorber in the UVB region and belongs to the category of photosensitizing additives. Although it does not have photosensitivity itself, it can increase photosensitivity when used together with arylalkyl ketone free radical photoinitiators (such as BP, ITX, 2-EA, etc.), so it is widely called synergist. agent. The mechanism of action of EHA is to promote the formation of free radicals, thus improving the effectiveness of photoinitiators.

As an amine synergist, the photoinitiator EHA is used together with a hydrogen-abstracting free radical photoinitiator to improve the efficiency of the photoinitiator by promoting the formation of free radicals. It is recommended that its addition amount be controlled between 2% and 8% of the total formula. The specific formula depends on the amount of active monomers in the acrylate system and the components of other additives. For more technical support, please contact Fscichem. Our company's product model is FsciPI-EHA

6. Suitable for UV curing coatings and ink systems

Traditional amine synergists increase the effectiveness of photoinitiators by promoting the formation of free radicals. This effect is achieved by coupling an amine synergist to a photoinitiator that reduces the activation energy of the reaction or by scavenging oxygen, thereby increasing the conversion of the initiator into active free radicals. Commonly used synergists include amines, such as N-methyldiethanolamine (MDEA), ethyl 4-dimethylaminobenzoate (EPD) and 2-ethylhexyl-4-dimethylaminobenzoate (EHA) etc. In addition to FsciPI-EHA, common models include Omnirad EHA; ESCALOL507
