Octadecyl Acrylate/Stearyl Acrylate CAS 4813-57-4 SA

Octadecyl Acrylate/Stearyl Acrylate is a white to light yellow waxy solid or liquid (depending on temperature change). It is mainly used as a functional monomer for UV curing coatings, adhesives and plastic modification, and its long carbon chain structure gives the product flexibility and hydrophobicity. It should be stored at low temperature away from light and avoid mixing directly with free radical initiators.
