EPOCAST 1633 A/B – BMS 5-28 TY 18 CL 2 REV AN –

Huntsman EPOCAST 1633 A / B is a bi-component epoxy syntactic paste. Intended for aeronautical applications, the EPOCAST 1645 FR A / B meets the aeronautical qualifications according to the specification: BMS5-28 Type 18, Class2. The EPOCAST 1633 A / B is flame retardant and specially designed for honeycomb filling where a very fast setting is required (working time 2 to 5min) - SPECIF BOE00113.

Color: Light blue / Viscosity: Soft-paste (1633 A: Soft-paste -1633 B: Soft-paste) / Density: 0,73 / Gel-Time: 2-5 min (at 25°C) / Cure-time : Gel-Time + 5h at 49°C or 2h at 66°C (or 3day RTV) / Compressive module: 270 KPa at 23°C / Compressive stregth : 44,8MPa à 23°C, 3,8MPa at 82°C / Lap shear strength: 9,6 MPa at 23°C.

The mixing ratio of EPOCAST 1633 is 100 to 50. It offers the advantage of being available in 50ml and 200ml cartridges. Because of its very short setting time, it is recommended not to perform manual mixing. Its viscosity and its conditioning in a two-component cartridge allow it to be easily injectable, especially during insert fastenings in honeycomb panels.
