Glass Microspheres
Details
Glass Microspheres are hollow glass spheres that when blended with resin produce a heat-resistant, lightweight, sandable filler. They add particles of air to solid materials and can displace 4 to 6 times the weight of resin. Used to reinforce strength or to fill gaps in targeted areas such as fabric weaves, butt joints, and the surface of core materials.
These hollow glass microspheres, sometimes called micro balloons or glass bubbles, are an ultra-lightweight naturally occurring, Aluminum Silicate that average 45 microns in diameter. Their size and structure provide greater tensile strength in comparison to other micro fillers. They are cost effective in the manufacturing of joint compounds, adhesives, auto body putty, resins, plastics and a variety of other composites.
- Blends easily to create a spreadable paste
- Low density reduces weight, lowers costs, and enhances properties for finished parts
- Exceptional density reducing agent due to low effective specific gravity (E.S.G.)
- Resin Filler
- Joint Compounds
- Auto Body Putty
- Adhesives

Product Data SheetResources
- Mix ratio is 3:1 (filler to resin by volume).
- Add filler after adding catalyst to resin.
- Fillers can affect the pot life of a resin, create a small trial batch first to determine how much working time you’ll have.
