USING SURFACE-MODIFIED CALCIUM CARBONATE IN ADHESIVE MATERIALS, SEALANTS AND/OR POTTING COMPOUNDS Russian patent published in 2015 - IPC C09C1/02 C08K3/26 

FIELD: chemistry.

SUBSTANCE: invention can be used in the production of adhesive materials, sealants and potting compounds. Surface-modified calcium carbonate is used as filler in said materials. Surface-modified calcium carbonate is formed in situ via a double and/or multifold reaction between calcium carbonate and the product of reacting said carbonate with gaseous CO₂, and the product(s) of reacting said carbonate with one or more moderately strong or strong H₃O⁺ ion donors and aluminium silicate, and/or synthetic silicon dioxide, and/or calcium silicate, and/or aluminium hydroxide, and/or sodium aluminate and/or potassium aluminate.

EFFECT: invention improves rheological and physical properties of adhesive materials, sealants and potting compounds, and improves safety when working with filling materials.
