Appli-Thane® 7800

0.3 W/mK

This thixotropic, easily reworkable aerospace urethane is ideal for bonding and staking applications. The material features a room temperature cure while also meeting NASA’s low outgassing requirements. With low modulus and low Tg, 7800 is a suitable substitute for many silicones in electronic applications.
