Properties and Applications

Ethyl 2-cyano-3,3-diphenylacrylate, another name Etocrylene, belongs to acrylic acid or the like UV light absorbers and is mainly used in making UV light absorbers in plastics, coating, dyestuff, vehicle glass, makeup, sun-screening agent. Because acrylate-based, two phenyls of this product and carbonyl can form a larger π key; thus, the structure shape of this product has extremely strong ultraviolet absorption ability.
