White Glass Microspheres Gallon

White Glass Microspheres are premium hollow glass spheres used as a lightweight filler for epoxy and polyester resin systems. They are specifically formulated to increase volume while significantly reducing the weight and density of mixed compounds, making them an excellent choice for fairing, filling, and surface finishing applications.

When mixed into resin, these microspheres create a smooth, low-density compound that spreads easily, sands effortlessly, and helps produce a professional-quality finish. They are commonly used in marine, automotive, aerospace, composite, and woodworking projects where reducing weight and creating a smooth surface are important.

White Glass Microspheres can be used alone or blended with other fillers such as Cabosil (fumed silica) or milled fibers to customize the consistency, strength, and sanding characteristics for specific applications.

Features & Benefits:

• Lightweight hollow glass microspheres reduce overall compound weight
• Creates smooth, easy-to-sand fairing and surfacing compounds
• Increases compound volume while using less resin
• Compatible with epoxy and polyester resin systems
• Excellent for filling low spots, fairing hulls, repairing composites, and cosmetic finishing
• Can be blended with other fillers to achieve custom viscosity and performance
• Ideal for marine, automotive, aerospace, composite, and woodworking applications

Mixing Instructions:

• Add microspheres slowly while stirring to prevent clumping and airborne dust.
• For polyester resin, mix the filler into the resin before adding the MEKP catalyst.
• For epoxy systems, mix the microspheres into the combined resin and hardener until the desired consistency is achieved.
• Add filler gradually until the mixture reaches the thickness required for your application.

Note: Always wear appropriate respiratory protection when handling fine powders and use in a well-ventilated area to minimize airborne dust exposure.
