Product Description

Product Description

 

Product Description:

The 801-C can be easily dispersed into powder with favorable fineness even in very short time. It is a kind of

white powder with high gel transparency and good performance in constancy reinforcement, thixotropic

and anti-depositing. It has the gelatin capability to the organic solution from medium to high polarity as

well as various hydrogenated oil and the composite linking substance, and it is capable of reproducing

thixotropic viscosity at a wide range of temperature.

Common chemical, physical properties:

Composition	Montmorillonite organic ammonium derivative
Appearance	Light white fine powder
Moisture content (%)	≤3.50
Dry powder fineness(through mesh 200)	≥99.0
Loss on ignition (900ºC,%)	30.0~32.5

Usage:

The 801-C product requires the high shear condition and the polarity activator to enhance its dispersion and

viscosity reinforcement.

Pre-gel method:

item	8%	10%	Dispersion Condition
Solvent	89.4%	86.7%
801-C	8%	10%	Medium speed mix, slow addition, high speed dispersion for 5~10 minutes
Ethanol 95%	2.6%	3.3%	Dispersed in high speed 15~30 minutes

This pre-gel could be added at any step of adjustment procedure, still the best time is before grinding.

Dry powder addition:

801C could be added as dry powder, it still needs polar activator to improve dispersing and thickening

properties.

• Add resin/solvent

• Add 801-C, disperse in high speed for 5~10 minutes

• Add polar activator (Ethanol or Acetone with 5% water), high speed disperse for 15~20 minutes

• Add wetting agent, pigment, grind and disperse (whipping, ball-milling, sanding) to the required

fineness

• Add other materials in system, disperse continuously to be average

Applications:

All solvent paint and coatings , sealing compounds, Iubricating grease and cast coatings ,etc.
