Kaolin for Agriculture

Intense sunlight causes sunburn on fruit and heat stress in plants, reducing yield and quality.

Kaolin is sprayed onto crops to form a white, breathable "particle film". This layer reflects harmful UV and Infrared radiation, keeping the plant cooler and preventing fruit burn, while still allowing photosynthesis light (PAR) to pass through.

  • Prevents Fruit Sunburn (Apples, Pomegranates, etc.)
  • Reduces Heat Stress & Water Loss
  • Deters Pests (Physical Barrier)

Performance Characteristics

High Reflectivity

Bright white coating maximizes sun reflection, lowering canopy temperature.

Fine Spray Mist

Micronized particles spray easily with standard agricultural equipment.

Safe Non-Toxic

Chemically inert, safe for plants, and washes off easily post-harvest.

Recommended Grades

Grades for agricultural applications — serving as a carrier, anti-caking agent, and physical pest deterrent in crop protection products.
