Photoinitiator EMK / Omnirad EMK / Speedcure EMK CAS 90-93-7

EMK is a new type of photoinitiator, mainly suitable for UV curing systems of acrylic monomers and oligomers. Absorber wavelength 245-375nm,It is mainly used to synthesize triarylmethane dyes, such as basic brilliant blue BO; it can also be used as a photosensitizer in the motion picture film industry; as a special optical material in the microelectronics industry; it can also be used as a rubber crosslinking agent.

Photoinitiator EMK Usage:

1. In practical applications, we can trace it back to the middle of the last century, when the paint industry was facing problems with drying speed and curing effects. With the development of photoinitiator technology, the emergence of EMK has brought light to the industry. For example, in the paint spraying process in the automotive manufacturing sector, the application of the photoinitiator EMK has greatly improved the drying efficiency and adhesion of the paint, making the appearance of the car more beautiful and lasting.

2. The amount added is generally in the range of 0.2-5.0%. This seemingly simple data actually contains profound scientific principles. If the amount added is less than 0.2%, it may not provide sufficient initiation activity, resulting in incomplete curing and affecting product quality. If it exceeds 5.0%, it may cause an excessive reaction, which not only increases costs, but may also cause problems such as excessive hardness and reduced flexibility.

3. According to the latest industry research report, in the production of some high-end inks, the precise control of the amount of photoinitiator EMK added can even be adjusted with an accuracy of 0.01%, in order to meet the needs of high-precision printing. This is different from the traditional concept of the addition range, which suggests that we need to make fine adjustments according to the specific production process and product requirements in actual applications.
