3M™ Glass Bubbles K46 have a density of 0.46 g/cc and an isostatic crush strength of 6000 psi. The general purpose K Series glass bubbles are the most economical 3M glass bubbles.
Application Guide
Listed below are key applications for K46 glass bubbles. Documents specific to the application are listed to the right.
Paints and Coatings
3M Glass Bubbles offer a variety of benefits to light weight, high-build elastomeric roof coatings, anti-condensation coatings, etc. Here are some of the benefits:
Lower viscosity, improved flow
Increased filler loading, reduced cost
VOC reduction
Chemical stability and inertness
Reduced dielectric constant
Thermal conductivity reduction
Temperature resistance
Thermal Insulating Additives
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.
