Product Description
EPOCAST® 1511 A/B is a high-density, non-flowing, two-part epoxy syntactic paste for edge filling honeycomb structures and metal fairings, as well as for bonding applications. The gray mixed system uses a 100:15 resin-to-hardener ratio by weight and provides a typical 40–60 minute work life for a 50 g mass at 25°C. It can cure for 24 hours at room temperature or be gelled at room temperature and post-cured for 5 hours at 52°C. After cure, typical properties at 25°C include 69 MPa compressive strength and 310 MPa compressive modulus. EPOCAST® 1511 A/B is qualified to BMS 5-28, Type 3.
Key features
- Non-flow edge filler: Paste consistency supports controlled placement in honeycomb edges and metal fairings.
- Practical processing window: Provides a typical 40–60 minute work life for a 50 g mass at 25°C.
- Flexible cure options: Supports a 24-hour room-temperature cure or an accelerated 5-hour cure at 52°C after gelling at room temperature.
Applications / Suitable for
- Honeycomb structure edge filling
- Metal fairing edge filling
- Bonding applications requiring a non-flowing epoxy syntactic paste
