5308 Epoxy
1.26 W/mK
An electrically isolating material, 5308 was designed specifically for underfilling, staking and encapsulating electronics on circuit boards, as well as potting and encapsulating power supplies, transformers, and coils. Featuring a 3-hour pot life, 5308 has good flowability, making it ideal for applications requiring a self-leveling material. The material meets NASA’s outgassing requirements, is resistant to solvents and chemicals, and is considered non-hazardous per D.O.T. regulations.
