Features and Benefits
Kaolin is used as a filler and pigment in coatings to improve the performance and reduce costs. Some of the benefits of using kaolin in coatings include:
Imparting gloss, smoothness, printability, and improved barrier performance in paper and packaging applications.
Enhancing the opacity, brightness, and whiteness of coatings.
It is also used in the manufacture of rubber. In general Kaolin is a light reinforcing filler used to produce soft compounds. to add strength, abrasion resistance, and rigidity. Some of the benefits of using kaolin in rubber include:
Adding strength, abrasion resistance, and rigidity to rubber particularly for light coloured compounds.
In construction products Kaolin can provide lubricity, reducing cracks from nails in gypsum wallboard
Extensively used in is personal care products, such as toothpaste and cosmetics, kaolin provides a range of benefits. Some of the benefits of using kaolin in personal care include:
Providing highly effective dental care when combined with delicately engineered perlite in toothpaste.
Offering a range of benefits in cosmetics, such as oil absorption, texture improvement, and skin cleansing.
Additionally Kaolin is used in adhesives and sealants as an extender or as a reactive or functional ingredient. Some of the benefits of using kaolin in adhesives and sealants include:
Improving rheology and reducing costs when used as a simple filler.
Offering moisture-sensitivity or improved reinforcement when using calcined and surface-modified or treated kaolin clay.

Industries
Adhesives and Sealants
Kaolin improves dispersion and mechanical properties in adhesives & sealants, improving tear resistance, tensile strength and high compression set in adhesives.
Kaolin being a naturally platy mineral provides barrier properties within sealants and can extend the tack of an adhesive by delaying the absorption of said adhesive into the substrate.
Kaolin improves rheology, reducing slump with improved flow, penetration, and adhesion. Kaolin has good acid resistance.
Kaolin is an effective extender of TiO2 and other pigments, thus increasing opacity or by reducing formulation costs.
Coatings
Kaolin is used in coatings to improve their performance and reduce formulation costs. It imparts whiteness, opacity, and brightness, and improves mechanical and optical properties. Kaolin also creates a barrier effect, which limits the penetration of water and corrosive agents into paints and coatings, leading to a reduction in bubble formation, corrosion, and peeling. Kaolin is commonly used in domestic coatings.
Elastomers
Kaolin is used in elastomers to improve the acid, alkaline and heat resistance of the products. It is used as a reinforcing agent to produce coloured soft rubber compounds to improve the strength, stiffness, and dimensional stability of rubber products. Overall, kaolin’s unique properties make it a valuable additive in rubber compounds, improving their mechanical, physical, and visual characteristics to ensure high-quality performance across various applications.
