Indoor moisture in domestic, commercial and industrial environments can lead to severe issues such as mold, structural decay, and compromised air quality. Traditional methods such as dehumidifiers and ventilation systems often fall short in effectively managing moisture levels. Anti-condensation paints provide a surface-level thermal solution that reduces the occurrence of condensation on cold interior walls.
3M™ Glass Bubbles are engineered hollow glass microspheres designed to offer exceptionally low thermal conductivity. Their internal gas-filled structure helps paint films retain higher surface temperatures, improving resistance to moisture condensation.

The structure of 3M™ Glass Bubbles
Incorporating 3M™ Glass Bubbles into anti-condensation paint formulations offers several key advantages:
Anti-condensation paints are particularly beneficial in high-humidity areas, including:
These paints are versatile, offering benefits across a range of applications to protect both industrial and residential spaces from moisture-related issues.
3M™ Glass Bubbles play a vital role in enhancing anti-condensation paints by improving thermal insulation and moisture resistance. Their ability to maintain higher surface temperatures makes them a strong choice for moisture-sensitive environments.
