RICHVIN 328 belongs to the family of substituted benzotriazoles which protect against ultraviolet radiation.
RICHVIN 328 has high solubility which makes it particularly useful for stabilizing castings, polyolefin, styrene and urethanes.
Compared to other RICH series UV absorbers, 328 is more solvent soluble, has better resin compatibility and wash fastness, is less volatile, and provides a degree of stabilization that is generally equal to or better than other members of the family.
