IOTA H21400 is a high-performance borosilazane adhesive with two-component, solvent-free formulation. Medium-temperature short curing balances speed and heat resistance.
With 1300–1500°C heat resistance and stable mechanical properties across the full temperature range, it excels at graphite bonding and is widely used for sealing metals, ceramics and composites, as well as high-temperature protective coatings.
Gray fluid applies easily with good gap filling. Strong adhesion at room and elevated temperatures: compressive shear strength >8 MPa at 400–1000°C, maintaining effective strength at 1500°C.
Flexible customizable packaging, easy storage, 1-year shelf life. Use in ventilated area. Suitable for industrial furnaces, aerospace and high-temperature kilns, delivering long-lasting high-temperature sealing.
