Product Details

3M™ Glass Bubbles K46 have a density of 0.46 g/cc and an isostatic crush strength of 6000 psi.

With an isostatic strength of 6000 psi, 3M K46 glass bubbles can be effectively used in ultra-deep water. They produce strong stable voids with low thermal conductivity, helping the coating achieve necessary compressive strength and insulation. Like all 3M glass bubbles, K46 glass bubbles are virtually insoluble in water or oil providing better utility in underwater applications.

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