Function & Applications:
Synacure 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.
Synacure 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 Synacure 754 are:
- clear coats for PVCfloors,
- top coats for woodparquets,
- plastic coatings in general (Compact Discs, cellular phones,),
- woodfurniture,
- UV-curable UV-stabilized
