- Features and Benefits
- Meets FST requirements
- Quick setting
- High mechanical performance
- Can be dispensed by meter mix machines
- Easy to apply and clean
- Qualified to BMS5-28 Type 18 Class 1
- No SVHC as defined under REACH
- Increase productivity by up to 50% with EPOCAST® 1648 A/B void filler. Available in bulk packaging for meter-mix dispensing or in cartridges, it can be applied faster than traditional mixing and application methods. It also sets quickly at room temperature so parts can move through production quicker. This low-density FST void filler can save weight in higher load applications, with up to a 40% improvement in compressive strength compared to competitive products. EPOCAST® 1648 A/B void filler is qualified to Boeing BMS 5-28, Type 18, Class 1 and De Havilland DHMS P1.30 Grade 2.
