SPHERIGLASS® Solid Glass Microspheres: Adhesives

Potters Industries offers a wide range of specified glass microspheres, specifically designed for controlling and defining bond line thickness in adhesives.

In general, 90% of the product fits within a very tight gradation specified (Product Specs Line). These products meet the requirements of Raytheon Spec HMS20-1776D and Hughes Spec SCGMS-53004.

Other grades of SPHERIGLASS provide performance benefits:

  • Higher solids formulas
  • Reduced VOC
  • Minimum viscosity rise-high flow
  • Reduced coefficient of thermal expansion
