Adhesives & Sealants
IMERYS is a major supplier of high quality mineral extenders to the sealant & adhesive industries throughout the world.
Our extensive range of products includes ultrafine kaolins, calcined kaolins, ball clays and calcium carbonates. In sealants & adhesives kaolins give good barrier effects and rheology control. The low surface hydroxyl content of calcined kaolins leads to a low moisture pick-up, resulting in excellent performance in moisture sensitive sealant applications. Calcined kaolins are also effective as structure building elements.
Finely ground calcium carbonates are used in a wide range of sealant & adhesive applications to improve rheological properties and reduce water or volatile content of the compound.
Some fine products are hydrophobised with stearate coating to reduce moisture pick-up, ease handling and improve dispersion.
