3M™ Glass Bubbles K15 , Small box (50 lb, 23 kg)

• Lower viscosity, improved flow
• Increased filler loading, reduced cost
• VOC reduction
• Chemical stability and inertness
• Reduced dielectric constant
• Thermal conductivity reduction
• Temperature resistance

3M™ Glass Bubbles K15 have a density of 0.15 g/cc and an isostatic crush strength of 300 psi.

With low density (0.15 g/cc) and isostatic strength good to 300 psi, 3M glass bubbles K15 are ideal for use in a variety of water buoyancy applications, including additives in buoys and moorings. Like all 3M glass bubbles, K15 bubbles are compatible thermoset resins like polyurethane and epoxy, and are virtually insoluble in water.
