In the manufacture of adhesives and sealants, precipitated calcium carbonate (PCC, CaCO₃) and lime (calcium oxide, CaO) are essential components of modern formulations. They influence viscosity, improve mechanical stability, ensure uniform processing and contribute to cost optimisation.
Coated variants of precipitated calcium carbonate (PCC) are used as rheology modifiers in various sealants, including PVC plastisol formulations used in the automotive industry and MS-, PU-, and PS-based sealants. Due to their easy dispersibility, high yield point and low viscosity, they greatly simplify the development of new formulations.
The products of the Calmit Group are specially tailored to the requirements of the adhesive and sealant industry.
Areas of application for adhesives and sealants
In industrial and construction adhesives and sealants, precipitated calcium carbonate (PCC) is used as a filler to specifically control viscosity, optimise rheological properties and improve adhesion. Ultrafine micronized lime products offer advantages in terms of stability and moisture control during the processing of PVC plastisol. In addition, natural fillers enable a reduction in volatile organic compounds (VOCs), thus supporting the development of sustainable formulations with a positive environmental balance.
