At Coventry cathedral, Araldite adhesive was used to bond its columns and fins, while at Sydney Opera House, Araldite adhesive was used to bond the rib sections of the shells, since a traditional concrete joint would have slowed construction, as it would need 24 hours to cure before stressing. [5]
The result was Aerolite, a urea-formaldehyde adhesive which unlike conventional glues of the time, resisted water and micro-organisms. Further research showed that gap-bridging hardeners incorporating formic acid enabled Aerolite to be used as an assembly adhesive. Aerolite was the first adhesive of its type to be invented and manufactured in ...
Copper has a very linear resistance–temperature relationship; however, copper oxidizes at moderate temperatures and cannot be used over 150 °C (302 °F). [citation needed] The significant characteristic of metals used as resistive elements is the linear approximation of the resistance versus temperature relationship between 0 and 100 °C.
Depending on the chemical basis, some adhesive types have limited thermal and chemical resistance and the mechanical properties of the bond are temperature dependent. Therefore, choose a type of adhesive that has been developed to have good thermal and chemical resistance, such as reactive hot melt adhesives.
Bonding at specific temperature, ambient pressure for specific amount of time; Post-bake/hard-cure to form solid BCB monomer layer; The wafers can be cleaned using H 2 O 2 + H 2 SO 4 or oxygen plasma. The cleaned wafers are rinsed with DI water and dried at elevated temperature, e.g. 100 to 200 °C for 120 min. [17]

The adhesive bonds the touch panel to the main liquid crystal display, and also bonds any protective cover, such as the lens, to the touch panel. After application, the adhesive is cured onto the device through ultraviolet light (UV), heat, moisture, or a combination, depending on the manufacturer and specifications. Major applications include ...
Thermal adhesive is a type of thermally conductive glue used for electronic components and heat sinks. It can be available as a paste (similar to thermal paste) or as a double-sided tape. [1] It is commonly used to bond integrated circuits to heatsinks where there are no other mounting mechanisms available.
