Appli-Thane® 7308
1.11 W/mK
The perfect choice for automated dispensing, 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. This material is thixotropic and maintains its form until subjected to temperatures exceeding 120°C.
