Bonding Capabilities

Comparing flex glue to super glue, it’s safe to say that the former is more flexible and versatile when it comes to bonding capabilities.

Flex glue can bond a variety of surfaces such as metal, plastic, wood, ceramic, and even fabric.

Super glue, on the other hand, may only work best for small projects involving non-porous materials.
