Redux is a thermosetting synthetic resin manufactured by the Resinous Products & Chemical Co., Washington Square, Philadelphia 5, Pa. According to the manufacturer, it is intended for bonding metal to metal and metal to wood. It was apparently intended to replace rivets in aircraft structural parts and recent information indicates that a British airplane, the DeHaviland Dove, is in production using this resin. The adhesive was originally developed in England by Aero research Ltd. Experience at this laboratory has been confined to use of the resin for bonding electrical grade silicon steel laminations. Very strong bonds have been obtained under properly controlled conditions. The bond strength is sufficient to tear 29 gauge (.014") steel when attempting to peel off individual laminations. The bond is sufficiently homogeneous to prevent leaks parallel to the plane of the laminations into a high vacuum system. Experiments at the laboratory have been designed to test the adhesive for use in bonding the laminations which form the pole tips and vacuum chamber lids for the synchrontron magnet.
