Highlights
  • Help maximize positive buoyancy (lift) - achieve some of the lowest density buoyancy syntactic foams for optimal performance
  • In design and construction, help enhance thermal management and improve application performance
  • Help reduce resin demand and minimize raw material usage
  • In exterior coatings, help provide high solar reflectance, good thermal insulation and surface protection
  • Help improve energy efficiency of exterior coatings, potentially leading to lower cooling costs
  • Help minimize cracking, sagging and shrinkage in adhesives, sealants and repair fillers
  • In interior and exterior coatings, they provide opportunities for higher solids and lower VOC levels

3M Glass Bubbles K15HSN are high-strength, low-density additives engineered to help improve survivability in low density applications. Featuring a density of 0.15 g/cc and a strength of 600 psi, these hollow glass microspheres are made from water-resistant, chemically stable soda-lime borosilicate glass. They help reduce density, enhance thermal insulation and contribute to energy efficiency. These versatile hollow glass microspheres are used in a wide range of applications, including construction, paints and coatings, and oil and gas industries.

3M Glass Bubbles K Series is specially formulated for a high strength-to-weight ratio. This allows greater survivability under many demanding processing conditions, such as injection molding. They also produce stable voids, which results in low thermal conductivity and a low dielectric constant.
