Bauspot GB1 contain 3M Glass Bubbles that are engineered hollow glass microspheres alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.

• Acrylic and industrial latex paints
• Solar reflective roof coatings
• Spackling, caulks, adhesives and more
• Epoxy coatings

The chemically stable soda-lime-borosilicate glass composition of Bauspot GB1 provides excellent water resistance to create more stable emulsions. They are also non-combustible and nonporous, so they do not absorb resin. And, their low alkalinity gives Bauspot GB1 compatibility with most resins, stable viscosity and long shelf life.

Technical details:

• Oil Absorption: 0.2–0.6 g oil/cc of 3M glass bubbles, per ASTM D281-84

• Packing Factor (Ratio of bulk density to true particle density): Averages about 60%.

• Volatile Content: Maximum of 0.5 percent by weight

• pH: 9.1-9.9 mixed with deionized water at 5% volume loading

• Appearance: White to the unaided eye
