Kaolin for Agriculture

UT-WHITE is used in the agrochemical industry as an inert mineral filler and carrier — not for what it does chemically, but for what it enables physically.

UT-WHITE hydrous kaolin serves as a functional diluent and carrier base in wettable powder (WP) pesticides, suspension concentrates (SC), granular herbicide formulations, and fertilizer blends. Its fine particle size, neutral pH, low oil absorption, and chemical inertness make it an effective powder filler that improves product flowability, dispersibility, and handling.

  • Inert carrier base for wettable powder pesticide formulations
  • Anti-caking agent and flow aid in granular fertilizers
  • Mineral diluent in suspension concentrates and dry flowable formulations

UT-WHITE Mineral Properties

Active Ingredient Free-Flowing Powder Kaolin Carrier Matrix

UT-WHITE provides inert carrier and flow properties in powder formulations

Performance Characteristics

Inert Carrier

Chemically inert, UT-WHITE absorbs and dilutes active ingredients without reaction, making it an ideal carrier base in wettable powder pesticide and herbicide formulations.

Free-Flowing Powder

Fine particle size (D50 4.5 µm), low moisture content, and platey particle shape give UT-WHITE excellent flow properties that prevent caking and improve dispensing in dry formulations.

Suspension Stability

Low density and fine platey particles help keep agrochemical suspension concentrates and wettable powders dispersed evenly in water, improving re-dispersibility and label consistency.

Recommended Grades

Grades for agricultural formulation applications, serving as inert mineral carriers, diluents, anti-caking agents, and flow aids in wettable powder and liquid-based products.
