中固化学®1173 is a 多官能 liquid photoinitiator, which can be used for the acrylic series of UV-curable varnishes on paper, metal and plastic surfaces. It is especially recommended for UV coatings that require only slight yellowing even when exposed to sunlight for a long time.
中固化学®1173 has good compatibility and can be easily mixed with other photoinitiators and prepolymers.
This product is used in conjunction with the light stabilizer Sinolstab®292, which can further reduce the yellowing of acrylic system polyurethane under outdoor sunlight.
