TenCate EX-1515
Cyanate Ester

Download datasheet (PDF)
Product description

TenCate’s EX-1515 cyanate ester resin system is unique in the industry in that it is able to achieve an extremely high level of cure conversion after a 250°F (121°C) cure. This level of conversion provides optimal mechanical properties, high radiation resistance, low moisture absorption/low outgassing while retaining unparalleled toughness, a low 244°F (118°C), 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/low loss values similar to other cyanate esters which allow its use in radome and antenna applications. TenCate’s EX-1515 can be post cured, free-standing, to increase its thermal performance for temperature critical structures.
