Etocrylene UV Absorber
Description
Etocrylene, C18H15NO2, is very effective at protecting plastics and coatings from the damaging ultraviolet radiation found in sunlight.
It offers excellent UV protection and good heat stability, a combination which makes it useful in many thermoplastic resins. Etocrylene contributes less color to coatings and plastics than many other UV stabilizers.
