Description

General description

Bis(1-octyloxy-2,2,6,6-tetramethyl-4-piperidyl) sebacate is a hindered amine light stabilizer (HALS) that is effective in retarding degradation through thermal and photo-oxidation process. It can be used in wood and plastic based coatings.

Application

Hindered amine UV light stabilizer.
Low basicity reduces interactions with acidic paint ingredients particularly effective in coatings based on alkyds.

Packaging

100 g in poly bottle
