Adhesives & Sealants

Mineral fillers such as calcium carbonate and dolomite are basic raw materials in adhesive and sealant formulations. Traditionally, the main reason for using filler was cost reduction. However, functional properties are increasing in importance as the market demands on adhesives and sealant products advance. Mineral fillers can be used to improve mechanical properties, resistance and rheology.

The range of fillers used nowadays is almost as wide as the range of adhesives and sealants available. From white marble powder for wet-room sealants, fine and coarse powders based on calcite for tile adhesives and grouts to surface-treated fillers for moisture-sensitive systems, Omya offers a wide variety of mineral fillers from a global network of local production facilities.

New developments include products that offer extremely low moisture content and uptake, and are designed specifically for reactive adhesives and sealants based on hybrid-polymer systems.
