Product description

EX-1515 cyanate ester prepreg resin system is unique in the industry in that it is able to achieve an extremely high level of cure conversion after a 121°C (250°F) cure. This level of conversion provides optimal mechanical properties, high radiation resistance, low moisture absorption, and low outgassing while retaining unparalleled toughness, a low 118°C (244°F), stress-free temperature, and long out time. The resin system excels in its ability to resist microcracking, even when subjected to thermal cycling and high levels of radiation exposure. EX-1515 also displays low dielectric and low loss values which makes it outstanding for radome and antenna applications. EX-1515 can be post cured, freestanding, to increase thermal performance for temperature-critical structures.
