Main features
- Low-Density, One-Component Epoxy Syntactic
- Up to 350 deg F Service
- Honeycomb Composite Potting
Product Description
LOCTITE® EA 9825 AERO is a low-density, one-component epoxy syntactic for honeycomb composite parts requiring high compressive strength at temperatures up to 350°F (177°C). The paste material is suitable for localized filling and reinforcement applications where weight and cured compression performance are important. It supports cure schedules at either 250°F (121°C) or 350°F (177°C), allowing integration with different heated aerospace composite processes. Documented uses include fastener or attachment potting and reinforcement of panel edges.
Key features
- Low-density epoxy syntactic: The cured material has a typical density of 0.72 g/cc.
- High compressive strength: Supports reinforced honeycomb composite structures and localized potting applications.
- Dual cure schedules: May be cured at 250°F (121°C) or 350°F (177°C) using the documented thermal profiles.
Applications / Suitable for
- Honeycomb composite parts
- Fastener or attachment potting
- Panel-edge reinforcement
