AF 191K .080WT 3M Structural Adhesive Film 48 in x 36 yd (1219 mm x 32 m)

The ready-to-fly structural adhesive film 3M™ Scotch-Weld™ AF 191 is characterized by excellent properties and ease of application. These adhesive films are available in a wide range of weights and media to meet design requirements without imposing an excess on material costs. Thanks to its high resistance to cracking and breaking forces, AF 191 provides a reliable, long-lasting bond on composites, metals – solid panels and cellular panels with a honeycomb structure, also in sandwich structures. Additionally, we also offer an unsupported version that can be used for meshing. It is compatible with many substrates and primers. In addition, AF 191 is characterized by excellent properties, including: does not absorb moisture when setting composite substrates. The following 3M™ primers are compatible with AF 191: 3M™ Scotch-Weld™ Primer EW-5000 Primer 3M™ Scotch-Weld™ EW-5000 AS for Structural Adhesives 3M™ Scotch-Weld™ Primer EW-5000 ET for Structural Adhesives 3M™ Scotch-Weld™ EC-3917 Primer for Structural Adhesives Our thermoset, easy-to-apply film is designed to meet a wide range of aerospace customer specifications and requirements. AF 191 is characterized by high resistance to cracking and breaking forces in various environmental conditions and is really easy to use. After hardening, it creates a bond of enormous strength, resistant to temperatures ranging from -67°F to 350°F (-55°C to 175°C). It is designed to work in many different environments, on many different projects. What is a structural adhesive film? The fewer rivets in the aircraft, the better! Structural adhesive film allows designers greater design freedom and part innovation, and also reduces the overall number of rivets needed to connect the entire structure. This thermoset, modified epoxy film adhesive can be used to bond a wide variety of substrates, including metals, honeycomb panels and composites. Structural adhesive films are available in a variety of weights and thicknesses, reducing the weight of the joint while maintaining structural integrity. The membranes are available in supported versions, which are usually used for monolithic joints and for sandwich-type cellular boards. They are also available in unsupported versions designed for meshing on cellular boards or honeycomb cellular panels. These films cure at temperatures ranging from 180°F (80°C) to 350°F (170°C). Due to the fact that the films are much less dirty and do not require mixing, they increase the process efficiency of the project. They are easier to use than standard paste adhesives. 3M at the forefront of innovation Adhesive bonding makes the structure “slimmer” because it allows the use of lighter composites, as opposed to metallic materials that were used in earlier designs. Structural adhesive films can be used anywhere metal and composite materials need to be joined. They have good erosion resistance, minimizing weight.
