5770 is very suitable, alone or in combination with oligomeric HALS, for the UV stabilization of tapes and thick items such as car bumpers and garden furniture. 5770 is recommended for polymers

such as polyolefins, PS, HIPS, ABS, SAN. It is also effective in polyurethanes, polyamides and polyacetals.
