Demand for composites is growing, and so, therefore, is the demand for composite bonding adhesives. As a result, Permabond offers a wide range of different adhesive technologies for bonding composites. Whether you require a rapid cure in seconds or need several hours to assemble parts, Permabond can help you find a bonding solution.

Common Adhesives Used
Epoxies
Permabond one-component heat cure epoxies, two-component room temperature cure epoxies, and flexible modified epoxies are popular for bonding composites. The following are a few examples:
- Permabond one-component ES569 is a thick epoxy paste, ideal for bonding carbon fiber where vertical application or gap filling is required.
- Permabond room temperature 2k epoxy ET5428 is a toughened epoxy with rapid strength development. Achieves handling time in under 45 minutes.
- Permabond MT3821 is a highly flexible modified epoxy adhesive with a Shore A hardness of 50.
Structural Acrylics
Both two-component and surface-activated structural acrylics are commonly used. For instance, consider TA4246, a surface-activated structural acrylic with very fast strength development. Activate one surface with Initiator 46 and then apply the adhesive to the other surface. Then you will achieve handling strength in under 5 minutes.
Polyurethanes
Two-component polyurethanes are a great choice for bonding carbon fiber interior trim.
