Three Bond 3732 - Anorganischer Keramik-Klebstoff - 200 g Tube

Three Bond 3732 – Inorganic Ceramic Adhesive Overview (A20177)

The Three Bond 3732 is an inorganic ceramic adhesive developed specifically for joints made of ceramic and metal. Available in a convenient 200 g tube, it serves as a fireproof adhesive and sealant for high-temperature components.

The adhesive is based on aluminum oxide as the main component and features a white color. With a 100% inorganic composition, it offers high insulation and is resistant to moisture as well as common chemical constituents. The maximum operating temperature is 1400 °C, enabling applications in the high-temperature segment.

Another relevant characteristic is the thermal conductivity of 2.55 W/m·K, which ensures controlled heat flow in ceramic-metal connections. The material hardness is given as approximately 200 HV, which supports robust mechanical load-bearing in the adhesive joint.

Suitable for Ceramic and Metal Joints

Ceramic Joints

In ceramic applications, the adhesive creates a dense, heat-resistant bond that resists temperature fluctuations and moisture – suitable for oven or firing processes as well as ceramic components in the chemical industry.

Metal Joints

For metal joints, the ceramic matrix contributes high resistance to heat and chemicals while ensuring reliable sealing.
