Glass Bubbles User Guide

Glass Bubbles are innovative, hollow microspheres that deliver lightweight, durable solutions for a variety of applications. Designed to mix seamlessly with resin, they create easy-to-sand, high-performance fillers that blend surface imperfections like scratches and pinholes. Ideal for industries requiring precision and ease, Glass Bubbles minimize weight, reduce costs, and enhance material properties without compromising on quality.

Uses for Glass Bubbles:

• Boat construction and repair

• Molding, fabrication, and repair of fiberglass laminates

• Acting as a thickening agent in resin

• Used as an adhesive, putty, or filler for fine cracks and holes

Features:

• Lightweight and easy to sand: Makes finishing projects faster and smoother

• Mix compatibility: Works with polyester, vinyl ester, and epoxy resins

• Combination friendly: Can be mixed with other fillers (e.g., glass microspheres or fumed silica) for tailored applications

• Simple application: Easy to incorporate into resin-based formulations

Needed Supplies When Working with Fillers:

• Resin

• MEKP (Methyl Ethyl Ketone Peroxide)

• Glass Bubbles

• Measuring cups

• Stir sticks

• Safety protection equipment (e.g., gloves, mask, eye goggles)

Application:

• Ensure the work area and resin are maintained within a temperature range of 70°F and 85°F.

• Operate in a well-ventilated area and use proper safety gear, including gloves and a face mask.

• Measure resin using a measuring cup.

• Gradually add Glass Bubbles while stirring to achieve the desired consistency.

• For polyester resin, add MEKP catalyst at a ratio of 1-2% of resin volume, adjusting for desired cure time and pot life.

• Mix thoroughly and apply the resin-Glass Bubbles mixture using a brush, spreader, or squeegee.

• Clean uncured polyester resin from tools using acetone.

Handling and Storage:

• Always store Glass Bubbles in a closed container in a cool, dry place with temperatures below 75°F.
• Keep away from sunlight and direct heat sources to maintain product integrity over time.
