Structural Epoxy Adhesives

Our epoxy bonding structural adhesives adhere to a wide variety of materials, from bare metals to plastics to foam. Known for their high tensile strength and excellent chemical resistance, they are the right choice when long-term exposure to high heat is required. These adhesives generally have long open times, but heat easily accelerates the curing process.

Benefits of Epoxy Adhesives

  • High strength adhesives and sealants for industrial, OEM, tier suppliers, and defense
  • Single- and two-component systems for high volume and convenience dispensing 
  • High-temperature performance 
  • Chemically resistant 
  • Bond a wide variety of substrates 
  • Low odor
  • Cure can be accelerated with heat 
  • Cryogenic version available 
  • Adaptable to all process needs:
    • Mix ratio options for flexibility and modulus 
    • Low viscosity, liquid formulations 
    • High viscosity, paste formulations 
What are Epoxy Adhesives?

Often referred to as "epoxy glue," epoxy adhesives generally tend to be viscous liquids or pastes, although self-leveling liquids are available. In general, epoxies have low odor when uncured and are less sensitive to slight variations in mix ratio.
