Solvay FM® 350NAU Adhesive Foam
Categories:	Polymer; Adhesive
Material Notes:	Description: FM® 350NA adhesive film is an aluminum-filled structural adhesive designed for elevated service temperatures. It was developed specifically for engine nacelle applications demanding continuous mechanical performance at 350°F (177°C). The FM 350NA adhesive product group optimizes bonding capabilities of metal honeycomb sandwich structures, especially those involving a perforated metal skin. Cytec’s BR®154 and BR® 6750 corrosion inhibiting primers are recommended for use with FM 350NA adhesive films in bonding aluminum details. FM 350NA is supplied on a light-weight glass carrier (FM 350NA) or as an unsupported film (FM 350NAU). Both forms provide superior flow properties without the use of asbestos as a thixatrope. FM 350NA adhesive, when properly cured at 340°F – 365°F (171°C – 185°C), exhibits impressive service properties, as exemplified by the test results reported in the attached tabulations. Features & Benefits: Structural properties from -67°F to 350°F (-55°C to 177°C) Superior resistance to long-term thermal environment exposure Unsupported film reticulates easily when heated Applications: Engine nacelle bonding Acoustic applications Information provided by Cytec, subsequently acquired by Solvay.
