Epoxy Resin Adhesives: Properties and Applications
Table 1: Key Properties of Epoxy Resin Adhesives
| Property | Typical Value | Significance |
| Viscosity | 500-50.000 cP | Determines application method |
| Pot Life | 5 min – 24 hrs | Working time before curing |
| Cure Time | 30 min – 7 days | Full strength development |
| Tensile Strength | 20-50 MPa | Structural bonding capability |
| Service Temperature | -40°C to 150°C | Thermal stability range |
Table 2: Comparison of Epoxy Adhesive Types
| Type | Cure Mechanism | Advantages | Limitations |
| One-Part | Heat-activated | No mixing, consistent quality | Requires oven cure |
| Two-Part | Room/heat cure | Versatile, fast curing | Mixing required |
| Structural Film | Heat/pressure | High strength, uniform thickness | Special equipment needed |
| Flexible | Room temp cure | Impact resistant | Lower strength |
| Conductive | Room/heat cure | EMI shielding | Higher cost |
