Film Adhesives

Redux® Adhesives

Hexcel manufactures a wide range of film adhesives, foaming films, primers and liquid shims for metal-to-metal and composite bonding.

Redux® adhesives are high performance structural adhesives designed for bonding metal or composite structures that once cured, form a permanent structural bond which is able to withstand harsh environments including elevated temperatures. Through using adhesives a continuous surface contact is achieved permitting a more even distribution of load. Redux® adhesives are provided in two product forms, either as films or as a liquid shim.  

Redux® film adhesives include epoxy, phenolic and bismaleimide adhesives, supplied in film form or roll. Once cured, the adhesives form a permanent structural bond which is able to withstand harsh environments, including elevated temperatures. The range includes adhesives for metal to metal and composite bonding which find wide application in transportation, recreation and construction industries.

Redux® Film Adhesives

The Redux® film adhesives range includes epoxy, phenolic and bismaleimide adhesives, supplied in film form or roll, and in various film weights. The rolls are protected by release paper and a plastic cover. Film adhesives are chosen according to their desired cure temperature, film weight and mechanical performance. They can be supplied either with or without an integrated carrier. The carrier helps maintain bond line thickness and flow of the adhesive during cure. Films are easy to cut into shape and to position. Being already mixed they just require heating to cure. Films provide a good way to cover a large surface with a even amount of adhesive, providing accuracy and control for the bonding process. Where bonding also requires filling of a gap between substrates, then a foaming film adhesive can be applied. 

Redux® Shimming Adhesives

Redux® shimming adhesives are a two component epoxy adhesive designed to offer general purpose bonding solutions for joining metal and composite structures and honeycomb. Shimming adhesives are supplied as room temperature and higher temperature curing adhesives suitable for structural bonding and for gap filling applications. The adhesives are supplied in various pack forms of 25 litre drums, 1 litre tins and 200ml cartridges. Shimming adhesives are best for use on areas where a film might be difficult to position or where the part cannot be exposed to high temperature during cure. 

Redux® Primers

Redux® primers are used to pretreat surfaces to provide protection and improve bonding for optimum effectiveness. They are fully compatible with Redux® film adhesives. All Redux® primers are free of chromium compounds.

Industrial Applications

Typical wind energy applications for Redux® film adhesives, foaming films, primers and liquid shims are root bonding and shell bonding.
