J-B Weld PlasticBonder™ Structural Plastic Adhesive

J-B Weld PlasticBonder™ is a quick-setting, two-part urethane adhesive system engineered for strong, lasting repairs across a wide range of surfaces—including thermoplastics, thermoset composites, carbon fiber, coated metals, and concrete. With a tensile strength of 3770 PSI, PlasticBonder™ delivers a hard, permanent bond that sets in just 15 minutes.

What Is J-B Weld PlasticBonder™?

J-B Weld PlasticBonder™ is a structural plastic adhesive formulated as a two-part urethane system. It is designed to bond difficult-to-adhere surfaces—such as carbon fiber composites, thermoplastics, and coated metals—where standard adhesives typically fail. PlasticBonder™ cures to a tan color and forms a rigid, permanent bond suitable for both repair and assembly applications.

What Surfaces Does PlasticBonder™ Work On?

PlasticBonder™ is compatible with a broad range of materials, making it one of the most versatile structural adhesives available. Supported surfaces include:

  • Thermoset plastics
  • Carbon fiber composites
  • Thermoplastics
  • Coated metals
  • Concrete
  • And more

This wide material compatibility makes J-B Weld PlasticBonder™ a reliable choice for automotive, construction, and industrial repair applications.
