GLASSCELL 10

Hollow glass microspheres based on soda-lime borosilicate, chemically stable, non-porous, and insoluble in water.
Specially formulated for compressive strength.
Low alkalinity: compatible with most resins, with long-term stability of properties and viscosity.
Non-flammable.
White filler.
Spherical shape:

Optimal volume-to-surface ratio
Low resin consumption
Lower viscosity at the same volumetric filler content
Reduced shrinkage and resin savings
Suitable for spraying, casting, and molding

Applications of Glass Cell:

Coatings: lightweighting before lamination of cellular foams, finishing prior to painting.
Filling function by increasing resin volume, syntactic foam.
Mechanical performance and chemical inertness.
