- Help maintain Class A paintable surface finishes, ideal for hoods, trunk lids, and body panels
3M™ Glass Bubbles S32HSN are high-strength, low-density additives specially formulated to be strong enough to survive processing. They are hollow glass microspheres made from water-resistant and chemically-stable soda-lime borosilicate glass. These hollow glass microspheres can help reduce density and offer enhanced thermal insulation for better energy efficiency. They are used in a variety of applications in diverse markets, including automotive, construction, paints and coatings, appliances, and oil and gas applications.

How 3M Glass Bubbles work
With an optimal balance of high strength and low density, 3M Glass Bubbles K15HSN help create materials that are versatile, lightweight and easy to work with in construction, paints and coatings applications, plus deep-water oil and gas buoyancy operations.
3M™ Glass Bubbles are finely dispersed, free-flowing powders consisting of thin-walled hollow glass microspheres. Made of soda-lime borosilicate glass, 3M Glass Bubbles are chemically inert, nonflammable and water resistant. Because spheres have the lowest surface area to volume ratio of any shape, 3M Glass Bubbles K15HSN pack tightly for high filler loading. Strong enough to survive processing, they can be incorporated into a wide range of polymers for density reduction. Far beyond lightweighting, the inherent properties of these microspheres provide a number of unique performance and processing advantages such as minimizing impact on viscosity and ease of incorporation.

3M Glass Bubbles in design and construction
High temperatures on roofs and exterior paints due to weather exposure and damaging infrared rays lead to increased indoor temperatures, resulting in higher cooling costs and reduced energy efficiency. 3M Glass Bubbles K15HSN in paints and coatings help enhance solar reflectance, reduce condensation, and potentially improve thermal management in applications.
3M Glass Bubbles in sealants, adhesives, and repair compounds offer lightweight solutions that help reduce sagging, cracking, and shrinkage, providing potential ergonomic benefits and enabling thicker applications. In repair compounds, they enhance the surface finish, making it smoother and paintable, while maintaining lightweight properties.

3M Glass Bubbles in oil and gas
The high pressures of deepwater environments place enormous challenges on flowlines, risers and critical equipment. 3M Glass Bubbles K15HSN are the newest addition to the 3M portfolio offering with an optimal balance of high-strength and the low density of the hollow glass spheres. They can be used as an additive and help enable the net buoyancy lift for syntactic foams used in deep-sea buoyancy applications such as buoyancy models, buoys, or buoyancy blocks for remote operated vehicles.
