Automotive Adhesives & Sealants

The use of adhesives for automotive applications is widespread, from something as small as a sensor to something as large as a vehicle chassis. Many high performance cars are produced with lightweight composite materials to keep the weight of the vehicle minimal. These composite materials are unable to be welded and the use of mechanical fasteners adds to the vehicle weight, as well as being unsightly and at risk of vibrating loose. Structural adhesives are very much a favourite amongst automotive industry professionals, as they allow different types of material to be joined together easily (such as composite to metal where welding would not be suitable). An added advantage is the rubber toughening present in structural adhesives which helps absorb vibration and impact forces.

Permabond has an extensive range of adhesive products suitable for under bonnet applications – such as formed-in-place gaskets, adhesive for core plug sealing, automotive hose bonding, heat exchanger sealing and filter end cap bonding. Electronic systems within the car also make use of many adhesives – such as potting and sealing electrical components, sensors, switches and relays, bonding electric motors and a whole host of other applications. Permabond supplies adhesives to the automotive industry worldwide, with many products specified by leading automotive manufacturers and Tier 1 automotive suppliers, who enjoy high quality cutting-edge products at very competitive prices.

Typical Applications:

Automotive Adhesives

  • Structural bonding of drive shaft and chassis
  • Sealing heat exchanger tubes
  • Bonding interior dashboard and trim
  • Gear box and sump cover gasketing
  • Potting and sealing of electronics and LEDs
  • Threadlocking and retaining bolts, pins and bearings
  • Bonding of sensors

Adhesive Key Features

Due to the high temperature resistance demanded by under bonnet applications, the Permabond range has been developed to include high-temperature resistant products, including anaerobics, epoxies and cyanoacrylates which can withstand temperatures of up to 250 deg C (480 deg F).

Structural products are available with rubber toughening to produce high strength, durable bonds, which are able to withstand the harsh conditions and vibration experienced on many under-maintained roads!

Permabond’s potting adhesives for electronics are very popular, due to the slight flexibility of these products. Expansion and contraction of electrical components, sensors or LEDs in the extremes of temperature need not be cause for concern, as the adhesive will flex and continue to maintain a high strength bond or seal without exerting any stress on these sensitive components.
