General description

2,2′-Methylenebis[6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol] is a benzotriazole based additive that is used as an ultraviolet absorber (UVA). It reduces degradation of the polymeric material by absorbing the UV radiation and converting it to thermal heat.

Application

It is majorly used as a UV filter in sunscreens and in photo-luminescent dyes for organic electronic based applications.
