Adhesives for Bonding Iron Substrates

Iron is soft, malleable, ductile, high strength and low cost. It is among the most abundant of all elements and the most widely used metal. It features thermal and electrical conductivity. Iron has a melting point of 1,532°C, is silvery gray in color and can be magnetized. It corrodes quickly upon exposure to moist air or elevated temperatures. Coating iron with other metals such as zinc can prevent rusting. Also plastic coatings are frequently employed for protecting iron.

Iron is used for a variety of manufacturing applications including:

  • Hulls of large ships
  • Machine tools
  • Pipes
  • Cars
  • Railways

Master Bond formulates one and two component epoxy adhesives for adhering iron to iron and iron to dissimilar substrates.

Consideration for Bonding Iron - High Temperature Resistance

Among the most widely used products are Supreme 42HT-2, Supreme 10HTND-3, EP17HT and Supreme 46HT-2ND2. Resistant to acids, bases, fuels, oils and solvents Supreme 42HT-2 exhibits toughness, superb thermal cycling capabilities and ambient temperature curing. 100% reactive, one part, no mix Supreme 10HTND-3 is noted for its exceptional shear/peel strength properties and non-flow characteristics. Master Bond EP17HT is easy to apply. Its compressive strength and Tg are outstanding. Durable Supreme 46HT-2ND2 is a two component epoxy compound that cures at a minimum of 250°F. It will withstand exposure to a wide range of chemicals and vibration, impact and shock.

Multiple formulations with different viscosities, colors, cure speeds, hardnesses, strengths, etc. are available for use for bonding iron.
