Redux adhesives aerospace structures

De Bruyne himself was undoubtedly no small factor in the spread of adhesive bonding through the European aerospace community. In addition to co-inventing the Redux family of adhesives, he was involved in the conceptual development of the Mosquito and numerous other aircraft and sponsored (and taught) a series of educational sessions on the benefits of structural bonding during the post-war years. 

Although many non-structural adhesives ean be solvent or water based, in aerospace applications, this format is usually the preserve of the surface protection and corrosion inhibiting primers. However, as indicated, there are exceptions and these are often those adhesives which are based on phenolic resoles (for example, Redux 775 Liquid) or on polyimides (for example, PMR -2). 

Finally, to gauge the complexity of gaining acceptance for any new structural adhesive by the aerospace market, all the data that have to be generated to meet relevant specifications in both Europe and the United States of America are shown for Redux 319 and Redux 319A (supported version). 

The tables and text below show the makeup of a typical range of commercially available structural adhesives (Redux from Hexcel Composites " ) and their supporting primers, syntactic pastes, and foaming adhesives. The whole range is considerably larger—to meet the demands of other industries such as road and marine transport, electrical, and electronics, and so on—but here only the key products for the aerospace market are shown.
