Reducing Agents for Buoyancy
3M Glass Bubbles K20 are used extensively in shallow water buoyancy
applications. Their low density (0.20 g/cc) provides reliable buoyancy,
and their high isostatic strength makes them an ideal choice when
processing or buoy depth requires more strength. And, like all 3M
glass bubbles, K20 bubbles are compatible with polyurethane, polypropylene
and epoxy, and are virtually insoluble in water.
Industrial
Explosives
The most versatile glass bubble, K20 bubbles are ideal for use in
bulk emulsion, packaged emulsion, water gel and slurry explosives.
Their high-strength provides protection against dead pressing while
their low density provides high velocity of detonation (VOD).
- True density: 0.20 g/cc
- Target crush strength (90% survival): 500 psi
- High fragmentation
- Inert, non-coalescing particles provide consistent performance
over time
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
