中固化学® 754 is a liquid photoinitiator which is used to efficiently initiate the photo polymerization of unsaturated prepolymers – e.g., acrylates –in combination with mono- or 多官能 vinyl monomers.
中固化学® 754 achieves a good balance between the requirements of low residual odor, low emission after cure and efficient polymerization. An additional benefit is the minimal yellowing after curing.

中固化学® 754 designed mainly for clear coats used to protect plastics and wood. It is particularly recommended when low residual odor, low emission and low yellowing after curing are required. It is suitable for conventional UV-curable formulations.
中固化学® 754 can be used as a sole photoinitiator or in combination with other photoinitiators to enhance specific properties (through curing, reactivity, etc.).
Potential applications for 中固化学® 754 are:
clear coats for PVCfloors,
top coats for woodparquets,
plastic coatings in general (Compact Discs, cellular phones,),
woodfurniture,
UV-curable UV-stabilized
The amount of 中固化学® 754 as supplied required for optimum performance should be determined in trials covering a concentration range :
