Small Particle
Size for
Class A Finish
|
Potters Industries supplies fine grade products for a variety of high performance applications in paints and coatings.
SPHERIGLASS® Solid Glass Spheres are available in particle sizes small enough to provide a Class A finish in topcoats.
With a density of 1.1 g/cc and a top particle size of 30 microns, SPHERICEL® Hollow Glass Spheres can also be used in this application. |

Adding microspheres to paint or coating formulations can reduce their cost. |
VOC Reduction
in
Solvent-Borne
Applications
|
Adding SPHERIGLASS® solid glass spheres or SPHERICEL® hollow glass spheres enables formulators both to reduce the Volatile Organic Compounds (VOC's) and to increase the solids and in their formulations.
When an irregularly shaped filler is added to a formulation, its viscosity increases. A spherical extender, by contrast, allows the formulator to reduce solvent content without increasing viscosity. When spherical extenders replace irregularly shaped fillers, in fact, formulation viscosity can be decreased. |
TiO2
Substitution
|
SPHERICEL® hollow glass spheres may be use to replace some of the TiO2 in a formulation. The hollow glass sphere redirects the angle of light, imparting opacity. Depending on the formulation, equivalent tint strength can be achieved with 2% - 5% replacement of TiO2. |
