2-Ethylhexyl-p-methoxycinnamate

Product Information

Molecular Formula:
C18H26O3
Molecular Weight:
290.40
Description
Very low volatile UV light absorber and stabilizer.Allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers. Low tendency to chelate allows its use in polymer formulations containing catalyst residues.
