The more popular name of 1-Hydroxycyclohexyl Phenyl Ketone is Irgacure 184, sometimes also known as photoinitiator 184. As one of the most commonly used photoinitiators, 1-Hydroxycyclohexyl Phenyl Ketone has good yellowing resistant ability and low oddor. Its absorption peak in methanol solution is 246nm, 280nm, 333nm, so it mainly absorbs short wavelength UV light. 1-Hydroxycyclohexyl Phenyl Ketone is used to initiate the photopolymerisation of chemically unsaturated prepolymers – e.g. acrylates – in combination with mono- or multifunctional vinyl monomers.

Experiment shows that: the longer the wavelength of the UV light is, the stronger the penetrability is, the easier it is to reach the deep layer of the film, while the shorter the wavelength is, the harder it is to reach the deep layer of the film. So 1-Hydroxycyclohexyl Phenyl Ketone is good for surface curing, if for thicker film formulation, it often co-initiates with irgacure 819 to achieve the balance effect both on surface and base.
