Appli-Thane® 7308

W/mK 1.11

The perfect choice for automated dispensing. A self-leveling injectable compound, Appli-Thane® 7308 maintains its dispensability for over 8 hours. The material can be cured during mass-reflow without disturbing the placement of components, thus eliminating several costly “component level” processing steps. It also eliminates the need for a separate cure cycle. The material meets NASA’s outgassing requirements and cures to a semi-flexible material with low modulus and a very low Tg.
