Unicell HMS Expanded Micro-Hollow Spheres
About Unicell HMS:
Unicell HMS are expanded acrylate copolymer microspheres. With particle sizes of 20, 50, and 100 micrometers, these microhollow spheres offer outstanding properties for a wide range of applications.

Use in interior paints:
Adding 8–12% Unicell HMS A20WI to water-based acrylate or styrene-acrylate paints produces thermally insulating paints with excellent elastic and bioinhibitory properties, as well as a low density of approximately 140 kg/m³.
Use in exterior paints:
Unicell HMS A100WI is recommended at addition levels of 5–8% to formulate exterior paints with benefits similar to those of interior paints.
Benefits of Unicell HMS in Coatings and Paints:
- Improved elasticity: Enables a flexible coating that better withstands movement and temperature fluctuations.
- Enhanced thermal properties: Improved thermal properties provide additional insulation and energy efficiency.
- Lightweight: Its low density makes it easier to handle and use.
- Antimicrobial properties: Thanks to improved water vapor permeability, bacterial and mold growth is significantly reduced. This makes the coatings ideal for hospitals, schools, and other places where hygiene is of the utmost importance.
The team at TRAMACO GmbH is pleased to introduce these innovative products to the market, as Unicell HMS will enable the company to offer customers even more high-performance and versatile paint and coating solutions going forward.
