Film adhesives


prepreg-and-adhesive-film-layed-up-on-tool_LoRez-120TenCate offers compatible matrix resins in a resin film form along with film adhesives.  These products are used for bonding composites to honeycomb, skin to skin bonding or used to provide a resin rich layer on the composite surface. TenCate's film adhesives can be provided in very light weights as low as 0.015 lbs per square foot (75 gsm). Common film weights are in the range of 0.03 to 0.06 lbs per square foot (150-293 gsm) and are typically offered with a lightweight scrim for easy handling.  TenCate's latest products include TenCate TC263 for high peel strength applications and TenCate TC310 for composite bonding applications.

Aerospace Film Adhesives

lay-up-of-nomex,-adhesive-film-and-prepreg-on-tool_LoRez-180TenCate’s line of aerospace grade film adhesives are used in a variety of applications including skin to core bonding, honeycomb core bonding and laminate/honeycomb bonding of composite structure. In addition to the film adhesives featured below, TenCate also provides composite surfacing films (TC235SF-1 series) which protects the composite surface and provides a smooth aerodynamic layer for coatings and lightning strike foil protection.  TenCate TC263 is a very tough 250°F/121°C curing film adhesive.  TenCate TC310 is a 350°F/177°C curing composite bonding film adhesive.

Industrial Film Adhesives

rolls-of-fabric_LoRez-100TenCate provides a complete line of epoxy film adhesives compatible with our line of industrial prepregs. TenCate’s line of industrial prepregs features flexible and low-temperature cure schedules, long out lives and the ability to be used as composite surfacing layers. Most of TenCate's film adhesives are compatible with our prepregs and some are actually derivatives of our matrix resins (resin films).
