High Tg Multifunctional Epoxy No Flow

N4000-29NF ("no flow") is based on the proven N4000-29 resin system. It is a high-Tg epoxy prepreg system that provides performance versatility and ease of processing. N4000-29NF is designed for bonding flex circuitry and bonding heat sinks to rigid circuit boards. N4000-29NF adheres well to most substrates. Its minimal, and consistent, flow is controlled through precise rheological and prepreg process control.|N4000-29NF has a 94 V-0 UL rating and meets the IPC 4101/98, 99, 126 & 129 slash sheets.
