IOTA R31000 is a solvent-free gray-black silazane ceramic precursor adhesive with viscosity of around 5000 cp. As a three-component system, it offers a 30-minute working time and fully cures naturally at room temperature within 5–7 days without heating furnaces, perfect for large workpieces and on-site maintenance. It withstands temperatures from 800°C to 1000°C with stable mechanical properties: tensile shear strength exceeds 4 MPa at ambient temperature, over 3 MPa at 400°C, and remains above 1 MPa at 1000°C. Its bond strength rises after long-term thermal aging and resists cracking or delamination after thermal cycling. It bonds and seals metals, ceramics and composites, and can be formulated into high-temperature resistant coatings. Customizable packaging ranges from 0.5L to 10L. The curing agent has a 1-year original shelf life and should be used within 6 months after opening. Ammonia gas releases when opening the lid, so operate in well-ventilated spaces.
