Adhesives for Bonding Steel Substrates

Today there are over 3,500 different types of steel available. Grades are varied by chemical processing to offer the precise mechanical, electrical, thermal and chemical requirements to meet customer needs. This list of specifications includes elasticity, ductility, strength, wear and corrosion resistance, hardness, etc. Categorization of steel is divided into:

  • Carbon steels
  • Alloy steels
  • Stainless steels
  • Tool steels

Steel is the most widely used of all metals. It offers high strength, durability, recyclability, and low energy to produce.

From automotive to energy to electronic/electrical to appliance to transportation, steel plays a vital role in maximizing product performance. Specific applications are as follows:

  • Shipbuilding
  • Tools
  • Heavy equipment
  • Pipelines
  • Bridges
  • Computers
  • Oil and gas wells
  • Wind turbines
  • Ovens
  • Engines
  • Transformer cores
  • Washing machines

Consideration for Bonding Steel - Chemical Resistance

Major products include EP21AR, EP30M4LV, EP41S-1HT, EP62-1 and EP125. Two component, low viscosity, room temperature curing EP21AR provides outstanding resistance to acids. EP30M4LV can withstand exposure to fuels, oils, bleach, 50% sodium hydroxide and 98% sulfuric acid. It has excellent flow, low exotherm and exceptional electrical insulation characteristics. EP41S-1HT is serviceable to +400°F and can resist gasohol. High performance EP62-1 has superior dimensional stability and a Tg >170°C. Its volume resistivity is >1014 ohm-cm. It cures rapidly at moderate temperatures and features a long working life. For prolonged service above 500°F, EP125 is the system of choice. Mechanical strength properties are impressive and durability exceptional.

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