Viscoexcel® 30-SG is an ultrafine precipitated calcium carbonate with primary particles of 30 nm. The particles are homogeneously coated with fatty acids to ensure good dispersibility in organic media. Viscoexcel® 30 - SG is used to control rheology in adhesives and sealants, providing high viscosity at low shear and good workability due to its shear-thinning effect at high viscosity. It also enhances the mechanical properties of structural adhesives.

Chemical Name: Calcium Carbonate

CAS Number: 471-34-1

Chemical Family: Calcium Salts, Carbonates

Synonyms: CaCO3, Calcium carbonate (CaCO3), Calcium carbonate (1:1), Carbonic acid calcium salt (1:1)
