This solvent-free grey two-component adhesive cures fast at medium temperature and withstands 1300-1500℃, serving two major industrial applications. It bonds and seals metal, ceramic and composite components for thermal equipment assembly; it can also be coated directly to make high-temperature anti-oxidation protective coatings. The paste with moderate viscosity ensures easy application with standardized curing process. It delivers reliable mechanical performance when bonding graphite, suitable for kilns, heat treatment fixtures and heat-resistant composite parts. Custom packaging and simple storage conditions are available. Ammonia releases upon opening, so ventilation is required during construction for regular supply to high-temperature and refractory coating manufacturers.
