Appli-Thane® 7800
0.3 W/mK
This thixotropic, easily reworkable aerospace urethane is ideal for bonding and staking applications where thermal conductivity isn’t required. Appli-Thane®7800 was designed specifically to have a 3-4 times longer pot life, half the cure time, and four times longer shelf life than standard aerospace urethanes. 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.
