?1. Caulks and sealants use high levels of calcium carbonate for desired performance and cost reduction 1.1?Reactive sealants often need very low moisture content for processing and shelf stability 1.2?Specialty engineered carbonates are incorporated to control rheology and mechanical properties 1.3?Higher brightness calcium carbonates offer better color match and surface finish ?2. Typical carbonates in caulks and sealants ?2.1 Water-borne caulks: medium PSD GCC ? 2.2Reactive sealants: fine PCCs and GCCs, treated carbonates
