BLS 1770


BLS 1770 (52829-07-9) is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections, but can also be used for articles with a high surface area such as films and tapes.  BLS 1770 provides effective ultraviolet light protection for applications demanding particularly high light stability.  It provides outstanding long-term stability by a radical trapping mechanism similar to that of hindered phenols.  Significant levels of stabilization are achieved at relatively low concentrations.  When compounded, BLS 1770 imparts no negative effects on a substrate’s initial color, its low dust, free-flowing form makes it exceptionally convenient to handle.
