TRA-BOND F113SC Black is a two-part epoxy system primarily used for connecting fiber-optic cables, as well as bonding in LED displays, lenses and other optical components. This room-temperature- curable material will achieve a typical Tg of 95ºC when post-baked at higher temperatures. It is a low-viscosity system with a black color that allows for easy polishing. The product is also physically and chemically resistant to impact and thermal shock, as well as water, weather and many organic and inorganic compounds.
