Adhesives, Caulks & Sealants
Kaolin Clays are widely used as functional fillers in adhesives, caulks, and sealants. Viscosity and rehology of adhesive systems is of paramount importance. The choice of the correct kaolin clay will affect these properties in the production and final application.
During production, when all ingredients are being mixed, it is desirable to have functional fillers that aid in the dispersion of the other ingredients by providing the correct amount of shear during mixing. The slight charge differential between the edge and surface of the clay aids in dispersion of the clay and other components of the mix, as well as improve the rheology. Kaolin clays are ideal, cost-effective, and functional fillers and pigments for adhesives, caulks, and sealants due to their particle size and platy structure.
During application, kaolin clay will provide the correct viscosity, prevent slumping, and fill voids, while providing visual contrast to easily identify where the material has been applied. The platy nature of kaolin also provides exceptional barrier properties to the caulk or sealants, as well as improving the strength of the adhesive film.
