Disclosed herein is a method for bonding dissimilar materials using an elastic adhesive to permit the bond to withstand variations in temperature and pressure. The use of elastic adhesive accommodates previous problems associated with large differences in thermal expansion coefficient between dissimilar materials, and provides a thermally and chemically stable materials combination that withstands large thermal shock loads, such as may be experienced in a space environment. Also disclosed herein is a method for attaching a coating to a structure. In particular applications, the coating may be (1) specular (greater than 98% specularity); or (2) RF reflective for use in applications including but not limited to high frequency satellite communications.
