- Paste Consistency for Application
- High Compressive Strength
Product Description
EPOCAST 1652-A/B is a two-component, low-density epoxy syntactic with a thick paste consistency for core filling, core splicing and localized structural reinforcement. The mixed system has a typical density of 0.8 g/cm³ and uses a 100:12 resin-to-hardener mix ratio by weight. It cures at room temperature or with an elevated-temperature post-cure and develops typical compressive strength of 55 MPa at 25°C. Documented applications include adding stiffness and strength to fabricated structures, including helicopter rotor blades, and reinforcing radii and corners in reinforced-plastic structures.
Key features
- Low-density syntactic system: The mixed material has a typical density of 0.8 g/cm³.
- Thick paste consistency: The semi-paste mixed form is suited to core filling, core splicing and localized structural build-up.
- Temperature-dependent compressive performance: Typical compressive strength at 2% strain ranges from 65.5 MPa at −55°C to 4.5 MPa at 177°C.
Applications / Suitable for
- Core filling for metal-skinned structures
- Core splicing
- Adding stiffness and strength to fabricated parts, including helicopter rotor blades
- Strengthening radii and corners in reinforced-plastic structures
