UV/EB Oligomer
XDT-1018
XDT-1018: 18 Functional Thioether Dendritic Acrylate Oligomer
XDT-1018 is a dendritic acrylate with an average functionality of 18. The hyper-branched structure of XDT-1018 imparts the unique combination of low diluted viscosity with unmatched chemical and thermal resistance. XDT-1018 is ideal in applications where withstanding exposure to the harshest conditions is paramount. Great for high-temperature applications because thermogravimetric analysis indicates the oligomer doesn’t decompose until 373°C. XDT-1018 has been INCI registered for use in cosmetic applications.
