Epoxy Adhesives Compounds for Bonding Stainless Steel

Stainless steel is available in many different grades. It offers exceptional resistance to corrosion and oxidation. Durable, high strength, aesthetically appealing, low maintenance and high/low temperature serviceability are among its many advantageous properties. It also is easily cleaned and sanitized. 100% recyclable stainless steel is noted for its ease of fabrication.

Used in a wide variety of industries, specific applications include:

  • Surgical instruments
  • Refrigeration equipment
  • Machine parts
  • Storage tanks
  • Passenger rail cars
  • Brewing equipment
  • Exhaust systems
  • Pressure vessels

Master Bond formulates adhesive systems to bond stainless steel to stainless steel and stainless steel to dissimilar substrates. These epoxy and polyurethane adhesive systems have convenient cure schedules, are easy to apply and can withstand exposure to harsh environments.

Consideration for Bonding Stainless Steel Substrates - Fast Cure Speed

Most popular fast curing adhesive systems include EP41S, SteelMaster 43HT, Supreme 3ANHT and EP51FL. Chemically resistant EP41S can withstand exposure to solvents, alcohols and fuels. Master Bond SteelMaster 43HT is a stainless steel filled two component epoxy offering high compressive strength and serviceability up to 400°F. Thermally conductive, electrically insulative Supreme 3ANHT requires no mixing and cures rapidly at moderate temperatures. EP51FL is cryogenically serviceable, has a convenient one to one mix ratio and is tough.
