Material Notes:
PERMABOND® ES578 is a single-part heat cured epoxy adhesive with excellent adhesion to metal surfaces, ceramics as well as composite materials. ES578 provides excellent thermal conductivity and bond strength. ES578 was designed for application requiring heat dissipation such as bonding aluminum heat sinks to ceramic headers. The cured adhesive has been designed to meet the fire retardancy requirements of UL94 V-0. Features & Benefits: Very good thermal conductivity Excellent resistance to vibration Easy to use – no mixing required High shear and peel strength High temperature resistance Good resistance to chemicals Designed to meet the requirements of UL94 Information provided by Permabond.
