BDT-1015

BDT-1015: 15 Functional Thioether Dendritic Acrylate Oligomer

BDT-1015 is a dendritic acrylate with an average functionality of 15. The hyper-branched structure of BDT-1015 imparts a unique combination of low diluted viscosity with unmatched chemical and thermal resistance. This is ideal in applications where withstanding exposure to the hardest of conditions is paramount. BDT-1015 is also great for high-temperature applications because thermogravimetric analysis indicates the oligomer doesn’t decompose until 372°C.
