Product Description
QC-8700 is a vinyl ester based sheet molding compound (SMC) designed for compression molding of components requiring high structural strength. It exhibits unusual toughness, and is suggested for applications subject to impacts and rough handling. QC-8700 is also suggested for applications requiring excellent fatigue resistance. It exhibits better temperature resistance than QC-8800.
