Kaolin (China Clay)

Kaolin for Ceramics, Paints, Paper and Industry

Kaolin, also called china clay, is a soft natural clay made mostly of the mineral kaolinite, a hydrated aluminium silicate. Processors mine the clay, then wash, refine, dry and mill it into a fine powder.

Its fine, plate-like particles give kaolin useful properties. It spreads evenly, fills gaps between other particles and stays chemically inert. As a result, manufacturers use it as a filler, extender and raw material in ceramics, paints, paper, rubber and plastics.

We stock kaolin produced in Kenya by Mineral Enterprises Limited, Nairobi, in 50 kg bags. Wisdo Merchants Chemical Division supplies it to manufacturers across Kenya and East Africa from Industrial Area, Nairobi.

Features and Benefits of Kaolin

• Fine particle size: Gives smooth textures in coatings, ceramics and compounds.
• Chemically inert: Does not react with most other ingredients in a formulation.
• Good filler and extender: Adds bulk and helps reduce the use of costlier ingredients.
• Plate-like particles: Improve surface smoothness, opacity and barrier properties.
• Heat resistant: Turns into hard, durable ceramic when fired at high temperature.
• Locally produced: Made in Kenya, which supports reliable regional supply.

Applications of Kaolin

Ceramics and Pottery

Ceramic makers use kaolin in porcelain, sanitaryware, tiles and pottery bodies. When fired, it forms a hard, durable ceramic.

Paints and Coatings

Paint makers use it as an extender pigment. It helps control sheen, improves suspension and supports opacity in emulsion paints. Explore our paints, coatings and pigments.

Paper and Board

Paper mills use kaolin as a filler inside the sheet and as a coating pigment on the surface. Consequently, the paper becomes smoother and prints better. See our paper and pulp chemicals.

Rubber, Plastics and Other Uses

Rubber and plastics compounders add it as a reinforcing or extending filler. It also appears in adhesives, sealants and agricultural products. For whiter fillers, compare it with our precipitated white filler powder. Browse our plastic and rubber additives.

Safety and Handling

Kaolin is not classified as hazardous in most cases. However, it is a fine mineral dust.

• Dust: Avoid breathing the dust. Use dust extraction or wear a suitable dust mask, especially during repeated handling.
• Eye contact: Dust may irritate the eyes. Rinse with clean water if contact occurs.
• Housekeeping: Clean spills with a vacuum or damp method rather than dry sweeping.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store bags in a cool, dry place, as the bag instructs. Keep them on pallets and away from moisture, because damp clay forms lumps. Use the product within 5 years of its manufacturing date.
