Hollow Glass Bubble Description
When added to aerospace adhesives, hollow glass microspheres serve as reinforcers while reducing weight. This maintains high strength and durability while creating a lighter final product. The bubbles also improve processing characteristics by reducing viscosity, making application easier and minimizing defects in bonded joints.
Applications
- Cyanoacrylates: Enhances strength-to-weight ratio and reduces density in fast-cure aerospace adhesives
- Acrylics: Improves performance characteristics in rapid-cure aerospace adhesive applications
