Details
3M™ Glass Bubbles K37 are lightweight hollow glass microspheres with a density of 0.37 g/cc and a crush strength of 3,000 psi. These general purpose spheres offer very good strength-to-density ratio and making them suitable for a variety of uses – coatings, adhesives, mastics, sealants and thermoset resin systems.
This general purpose Glass Bubbles grade is used for coatings, adhesives, mastics, sealants, and thermoset resin systems.
- Decreases weight in paints and thermosets to improve efficiency and may lower costs
