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

RBH is the UK’s leading supplier of Acti-Gel®.

 

Acti-Gel® In Detail:

Acti-Gel® 208 is a highly purified, Magnesium Aluminium Silicate product with unique properties. The material emanates from Attapulgite Clay, which when processed transform into homogenous rod-shaped particles, with pseudo-nano dimensions.

The Process

Stability at rest in thixotropic or pseudo plastic liquids is often the result of a three-dimensional network of tiny particles at rest. The homogeneous shape of the Acti-Gel® 208 particles allows very fast formation of such a network in water-based products, preventing settlement and water floatation highly efficient:

  • Upon shear (spraying, pumping, tooling, brushing or pouring) this network is broken down completely.
  • This results in a very low viscosity under shear.
  • As soon as the water-based product is at rest the network is formed again very fast – in some cases in less than 0.2 seconds.
  • This results in the reconstruction of a high viscosity (stabilisation, preventing sagging) after application.

The Result

  • 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® has also been found to act as a reinforcing filler in several applications.
