This highly toughened resin system offers the same processing advantages as NT-350 but is toughened in order to provide high resistance to impacts.
The NT-350 HT offers excellent surface finish for both Vacuum Bag Only (VBO) processing and autoclave processing.
NT-350HT offers unlimited out-time (no refrigerated storage) with zero change in process parameters over time. NT-350HT allows the parts builder to efficiently build large out-of-autoclave structures with near zero voids and without complicated debulking processes or elaborate cure cycles.
While NT-350HT was designed for OOA processing, it is perfectly suitable for in-autoclave processes. NT-350HT is an ideal prepreg for aerospace secondary and primary structures, space and satellite structures and radomes.
