In many industrial scenarios with strict requirements for material performance, the IOTA H21400 borosilazane-based adhesive has become an ideal choice for solving high-temperature bonding and sealing problems, thanks to its unique advantages. The IOTA H21400 features medium-temperature curing and a short curing time. This characteristic significantly improves production efficiency and reduces the time cost of waiting for the adhesive to cure, fitting well with fast-paced production processes. Its temperature resistance is truly remarkable. It can operate stably in high-temperature environments ranging from 1300 to 1500°C. Even under extreme high-temperature working conditions, it can ensure the normal operation of the bonded and sealed components.
This adhesive is a gray two-component product and is solvent-free. This not only makes the usage process safer and more environmentally friendly but also avoids performance instability caused by solvent residues. It has a wide range of applications and can easily achieve bonding and sealing between metals, ceramics, or composite materials. Whether it is the connection of metal and ceramic components in the aerospace field or the sealing of composite materials in industrial manufacturing, it can demonstrate excellent bonding effects. At the same time, it can also be used to prepare high-temperature resistant coating materials, providing reliable protection for various materials vulnerable to high temperatures.
In terms of technical parameters, it has a gray appearance and a viscosity ranging from 3000 to 4000cp, with good fluidity, which is convenient for uniform application and construction. When used for bonding graphite materials, the bonding strength at room temperature is greater than 5MP. The compression-shear strength is greater than 8MPa at 400°C, 800°C, and 1000°C, and greater than 2MPa at 1500°C, fully demonstrating its strong high-temperature bonding performance. The curing condition is to heat up to 170°C with the furnace, cure for 2 hours, and then cool down with the furnace. In terms of packaging, according to customers' needs, plastic drums with a capacity of 0.5L to 10L can be used. When storing, the sealant should be placed in a cool and dry place, and the shelf life is 1 year. It should be noted that after the base adhesive is placed for a long time, ammonia gas will escape when the bottle cap is opened. It is recommended to use it in a well-ventilated environment. Choose the IOTA H21400 to provide a solid guarantee for your high-temperature applications.
