  • Multi-Substrate High-Adhesion Bonding

Product Description

3M™ Scotch-Weld™ Epoxy Adhesive 2214 Hi-Temp New Formula is a one-part, 100% solids, aluminum-filled epoxy adhesive designed to deliver high strength at elevated temperatures. Curing at 121°C (250°F), this deaerated, paste-consistency adhesive is specifically formulated for bonding metals and high-temperature plastics such as fiberglass-reinforced plastic, polyester, and phenolics. It is engineered to maintain robust performance in demanding environments requiring higher strengths between 82°C and 177°C (180°F to 350°F).

Key features

  • High-temperature strength: Maintains strong, reliable bonds in demanding thermal environments from 82°C to 177°C (180°F to 350°F).
  • One-part, heat-curing formula: Eliminates mixing requirements and cures thoroughly in 60 minutes at 121°C (250°F).
  • Versatile substrate bonding: Effectively adheres to metals and various high-temperature plastics, including fiberglass-reinforced plastics and phenolics[cite: 10].

Applications / Suitable for

  • Bonding metals in high-temperature environments
  • Adhering high-temperature plastics such as fiberglass-reinforced plastic, polyester, and phenolics
  • Applications requiring high structural strength between 82°C and 177°C (180°F to 350°F)

Work life @25°C
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate. It is based on the change in viscosity and it can rely on the application requirements.
1.1 hours
Thermal Properties
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
0.422 W/m.K
Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
