Acti-Gel® – Alternative to Bentonite Clay

Buy Acti-Gel® From The Leading Supplier in UK & Ireland

Acti-Gel® is a superior alternative to bentonite clay in a range of applications.


Acti-Gel® is an inorganic thickener presenting significant benefits within water-based coatings, ceramic glazes, and agricultural products.

Acti-Gel® (Magnesium Aluminium Silicate) offers excellent rheology modification, anti-settling and thixotropic thickening solutions. It also:

  • Eliminates sedimentation
  • Decreases synerese
  • Prevents settlement
  • Excellent stability

Common Applications

  • Adhesives & Sealants
  • Ceramics
  • Coatings
  • Environmental
  • Specialities

Acti-Gel® offers the following benefits:

Acti-Gel® 208 is a highly purified, Magnesium Aluminium Silicate product with unique properties. Emanating from attapulgite clay, Acti-Gel® 208 prevents settlement and water floatation in a variety of applications:

  • Water-based liquids, slurries and suspensions with ions and/or solids (with charge) can become highly pseudo plastic by addition of 0,01-3% (w/w) of Acti-Gel® 208.
  • Water-based products show excellent workability, spray-ability, self-levelling properties, green strength and self-compacting properties since the viscosity is very low by the shear during application.
  • Viscosity under shear is lower than with cellulose ethers.
  • Once applied, viscosity will recover by absence of shear, resulting in unmatched stability (no bleeding, no segregation, high layer thickness, no syneresis, and no colour float).
  • The dosing rate of Acti-Gel 208® depends on the amount of ions and/or solids with charge in your water based product. The level needed will be lower at high concentrations of ionic charges.
  • The time needed for the viscosity to recover after applying shear also depends on this concentration of ionic charges. Recovery will be faster at higher concentrations of charge.
  • Acti-Gel® also acts as a reinforcing filler in several applications.
