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.
