| Ceramabond 685N  Ceramabond 685N, a new high temperature ceramic adhesive developed by Aremco Products, Inc., is now used to bond ceramic honeycombs to metal frames used in the construction of gasfired ceramic radiant heaters. Ceramabond 685N is a single part, dispensable, zirconium silicate based adhesive and sealant system that bonds tenaciously to galvanized metals, dense ceramics, and ceramic cloth, paper and rope products. It offers a maximum temperature resistance of 2500 °F (1370 ºC). Ceramabond 685N is an easy-to-apply, fast-setting, thixotropic, water-dispersible paste, which contains no asbestos or volatile organic compounds. Curing is accomplished by air drying for 2-3 hours and then heating gradually to the operating temperature of the assembly or by heating to 200 ºF for 2-3 hours. After curing, Ceramabond 685N exhibits a tensile-shear strength of 500 psi, a linear shrinkage of less than 2%, and exceptional chemical, moisture and thermal shock resistance. Typical applications for Ceramabond 685N include bonding ceramic honeycombs to radiant heaters and catalytic converters, high temperature ceramic rope and gaskets to galvanized ductwork, spark igniters, and general ceramic-to-ceramic and ceramic-to-metal bonding. write your comments about the article :: © 2008 Construction News :: home page |
