Enhancing adhesives & sealants with Omyasphere 900 lightweight fillers

Supplied by Omya

Omyasphere 900 series are lightweight fillers based on hollow glass microspheres designed for polyurethane, silyl-modified polymers, and silicone adhesives & sealants. 

 

These spherical, hermetic microspheres combine low density, high compressive strength, and brightness to enhance formulations. 

 

They reduce weight, improve rheology, increase yield, and ease application while lowering transport emissions. 

 

A case study shows that adding 4.7% Omyasphere 938 to oxime silicone sealant reduces density by 21% without compromising mechanical or rheological performance.
