3M Glass Bubbles for Paints and Coatings
From single family homes to large industrial plants, paints and coatings are the first line of protection for the buildings that shelter our businesses and lives. And weathering the elements year after year – while keeping down initial and long-term costs – requires the right materials.
3M™ Glass Bubbles provide a high performance, cost-effective alternative to conventional fillers in a variety of paints and specialty coatings. These hollow glass microspheres are used as density-reducing paint additives, helping lower formulation weight and viscosity, and can contribute to a variety of functional benefits ranging from scratch resistance to solar reflectivity. Available in a wide range of strengths, densities and particle sizes, 3M Glass Bubbles can help you meet the performance and processing demands of your application.
- Acrylic and industrial latex paints
- Solar reflective roof coatings
- Epoxy coatings

Boost PerformanceThe high strength, low density and unique physical properties of 3M Glass Bubbles can provide a number of advantages compared to paints and coatings formulated with conventional, irregularly-shaped fillers.
- Improved abrasion resistance (depending on product grade)
- Reduced thermal expansion and shrinkage
- Uniform spherical shapes help improve flow that can then provide for a more efficient process and easier application
- Higher volume loading and weight reduction
-
Help Save EnergyCool isn't just a matter of comfort. Effective solar management – or the lack of it – can have a significant impact on your bottom line. Testing shows that solar reflective roof coatings formulated with 3M Glass Bubbles can offer a number of performance and cost benefits compared to typical "cool roof" coatings.
- Higher total solar reflectance
- Higher thermal emissivity (ability to give up heat)
- Lower inside temperatures
- Lower cooling costs

3M Glass Bubbles for Construction
In construction, 3M Glass Bubbles used as a paint and coatings additive help create building materials that are versatile, lightweight and easy to work with. Their low density enables higher filler loading, as well as a lower cost per volume compared to many conventional fillers. 3M Glass Bubbles can also help improve sandability and reduce shrinkage and warpage in spackling compounds, wood composites and other materials – helping you reduce rework.
They withstand the high temperatures and stresses of processing conditions such as liquid phase polymer processing, high-viscosity melt compounding and high-pressure injection molding.
- Spackling, caulks, adhesives
- Potting compounds
- Preformed concrete
- Engineered wood
