Bentonite HEMINGS F350C NEW

HEMINGS® F350C

Rheological Additive for Aqueous System

General information：

HEMINGS®    F350C   is   a  refined  silicate  clay   r heological  additive  suitable  for  the thickening and flow  control of aqueous  systems.  

HEMINGS®F350C additive can  be used to prepare high concentration dispersions that develop their full viscosity in the final filled system.

Properties：

Key properties: rheological properties

l Is a cost-effective thixotropic additive for filled

l Provides shear-thinning viscosity and stable

l Improves slump or sag resistance

l Does not retard drying; has fast water release

l Acts as suspending agent, preventing hard settlement

l Is bacteria- and enzyme-resistant

Incorporation:

HEMINGS®   F350C  additive  can  be  added  dry  to  the  formulation  along  with  other mineral components and will develop  its gelling  ability  under  high  shear  dispersion conditions. It is stable within the pH range 6 - 11.

For improved performance and easier incorporation, it is better to prepare a pre-gel ataround 10 % solids, preferably in warm water.

High-shear forces are required for 20 - 30 minutes (high-speed disc impeller at 15 - 20 ms–1 typical peripheral speed). The water should be free from salt and surfactants. The pre-gel can then be added to the system as required and is easily incorporated under moderate shear but will only become fully active if it experiences further high shear in the presence of other solid materials (e.g. pigments and fillers).

Levels of use:

The level of addition depends on the desired properties of the system. Typical levels range from 0.3 - 2.0 % HEMINGS®  F350C additive, based on the total formulation.

Storage:

l Store in dry location.

l HEMINGS®   F350C will absorb atmospheric moisture if stored under high humidity conditions.
