Transport Industry Adhesives

Planes, trains, and automobiles all require adhesives for a broad range of bonding applications. In many cases, welding, brazing, and mechanical fasteners are simply not suitable. Planes use many lightweight composites which cannot be welded and using bulky mechanical fasteners would add to the component weight, making the use of adhesives in the aviation industry widespread. Trains and buses are adopting similar lightweight materials in a bid to increase the fuel efficiency of vehicles and of course looking at similar joining techniques. Adhesives are vital for locking nuts and bolts together to prevent vibration loosening, They also help prevent parts seizing through corrosion, so if at some future stage maintenance and repair work is carried out, parts can be disassembled easily.

Permabond adhesives are specified by a number of aerospace, bus, and train manufacturers worldwide, along with many of their associated maintenance and repair contractors

Typical Applications:

• Interior and exterior panel bonding
• Handrails, seat trays, overhead lockers
• Bellows between carriages
• Chassis
• Track maintenance
• Maintenance, repair, and overhaul of trains, trams, buses, and planes
• Kick plates and grips

Adhesive Key Features

For exterior panel bonding, Permabond offers high strength, rubber toughened adhesive products that have low shrinkage (to prevent witness marks through thin metal sheeting), good gap-fill ability, and superb adhesion to aluminum – as well as a quick working time so parts do not have to be clamped for hours, taking up valuable factory space.

Products include MMAs, such as Permabond TA4210 (available in Europe, The Middle East, and Australia) and TA4810 (available in The Americas and Asia), MS polymers, (see the MS359 series) if faster cure speed is desired consider modified epoxies such as MT3821, and polyurethanes.

Permabond works hand in hand with transport authorities, often producing custom formulations to meet strict formulation and specific performance requirements required in certain countries.
