Usage

Photoinitiator 1173, the formal name is 2-Hydroxy-2-methyl propiophenone, short for HMPP, is one of the most widely used non-yellowing UV photoinitiators. It plays an important role in photocuring technology, because of its advantages of high initiation efficiency, good thermal stability, yellowing resistance, good storage stability, etc.
As a liquid photoinitiator, PI 1173 has excellent compatibility and can easily mix well with other photoinitiators and prepolymers. For example: PI 1173 is soluble in toluene, acrylate, methacrylate, etc., and easy to mix with resin. Its absorption wavelength is 240nm~340nm.
Photoinitiator 1173 belongs to free radical type I photoinitiator, which is mainly used for UV curing reaction, such as UV curable coatings, UV curable ink, UV curable adhesive and other products as radiation curing initiator.
Photoinitiator 1173 has been tested as an ultraviolet curable varnish of acrylate series for paper, metal and plastic surfaces. Particularly recommended for UV coatings requiring only slight yellowing even when exposed to sunlight for a long time.
