We are the first manufacturing

glass microspheres

with a sol-gel technology

Get your materials light, smart and sustainable

What do we do ?

GAMMA Tech formulates and manufactures

solid and hollow glass microspheres with sol-gel technology

for paints, coatings and composites.


Disruptive process

Sol-gel technology.

Customization options

Our sol-gel technology offers numerous customization options : specific formulations, organic/inorganic hybrids…

Low-carbon footprint

Unlike conventional glass microspheres manufacturing, our ambient temperature process has a low-carbon footprint.


Glass microspheres are of two types, solid (also known as glass beads) or hollow (also known as glass bubbles) ; they are used as fillers across various industries, including transportation, building and construction.

Our focus applications are : decorative paints, road marking, cool roof coating and SMC/BMC composites.

Our product roadmap includes R&D activities in combining microspheres with specific matrix such as shock-absorbing and self-regenerating polymers.

Decorative paint      

SMC/BMC Composite

Road marking

High performances and processing benefits

Filling paints, coatings or composites with our microspheres provide unique performances and processing benefits like : weight reduction, thermal insulation, retro-reflectivity, solar reflectance…
