A while back I had a Henkel rep visit me to discuss the Hysol range of adhesives. From what he explained 9462 "Aeropoxy" is a product certified to be used in the aviation industry, and the license for this approval was held exclusively by the original American manufacturer, this product is now part of the Hysol range and the license maintains that the product can only be sourced form the original supplier, under the Hysol 'brand' who now have the sole selling rights. In essence this means the product is priced in a manner which the original product manufacturer dictates.

Other Hysol products are not part of the agreement and over the years they have developed their own versions like 9464 which have almost identical properties to 9462 "Aeropoxy".

The Henkel rep also said that although the 9462 product is very good, it is not really the best adhesive for our application as the materials and composites we use to build with are subject to flexing, and 9462 is not tolerant to this. Other products are better designed for this including Methacrylates.
