VISCOGEL X4

VISCOGEL X4 belongs to the conventional type of organoclays group, which requires mechanical energy, shear forces applied with a good dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organobentonite platelet stacks.
While heat is not essential in most cases, processing temperatures above 20°C are preferred. 

VISCOGEL X4 is a new high performing, highly effective rheological additive for solvent-borne systems of low to medium polarity that gives excellent thixotropic effect, sag control, good levelling and prevents pigments from long-term storage settling.
The nature of VISCOGEL X4 is a highly purified bentonite clay, organically modified with a quaternary alkylammonium compound. 

VISCOGEL X4 is a bentonite clay grade, organically modified with a quaternary ammonium compound. 
VISCOGEL X4 is acts as a rheology modifier for solvent-borne systems of low to medium polarity. 

VISCOGEL X4 requires mechanical energy, shear forces applied with a good dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organobentonite platelet stacks. 
VISCOGEL X4 shows good performance in solvents like aliphatic mineral spirits and aromatics. 

VISCOGEL X4 is used in manufacturing adhesives. 
VISCOGEL X4 is recommended for applications with strong anti-sagging properties (at dosage level up to 3.0%). 
VISCOGEL X4 is complies with ISO 9001 regulation. 

VISCOGEL X4 offers thixotropic effect, sag control and good levelling. 
VISCOGEL X4 is recommended for oil-based paints and stains for industrial or architectural industry. 

VISCOGEL X4 is also suitable for architectural & industrial paints (at dosage level 0.1% - 0.5%), primers & printing inks (at dosage level 0.4% - 0.8%), and for applications with strong anti-sagging properties (at dosage level up to 3.0%). 
VISCOGEL X4 has a shelf life of 36 months.

VISCOGEL X4 is always recommended to determine the proper level of addition by experiment. 
Either defect or excess of chemical activator would result in poorer viscosity development.

Several methods can be used to incorporate VISCOGEL X4:

The “direct add” technique:
VISCOGEL X4 is added directly in powder form to the solvent/resin mix, before pigment addition and milling.
Surfactants have to be added the last.

The “pregel” technique:
VISCOGEL X4 is pregelled as described above in a suitable solvent at a 5-10 % concentration, with a polar activator.
The activated gel is then added to the binder solution and stirred. 
After pigment addition the mix is finally milled.

Dosage of VISCOGEL X4:
Level of addition strongly depends on the type of system and on the degree of thickening or other properties desired. 
For architectural and industrial paints, typical levels are between 0.1 % and 0.5 % of VISCOGEL X4. 

For primers and printing inks, higher levels are required (0.4-0.8%). 
For strong antisagging properties, up to 3.0 % can be used.

Applications of VISCOGEL X4:
VISCOGEL X4 is used in a wide range of manufacturing processes, for oil based paints and stains (either industrial or architectural), printing inks, lubricating greases, adhesives, cosmetic and personal care products, to give the desired rheological control to the system.
VISCOGEL X4 shows particularly good performance in solvents like aliphatic mineral spirits and aromatics.

Storage Stability and Packing of VISCOGEL X4:
VISCOGEL X4 do not deteriorate in a significant way in a 36 months period. 
Storage is advisable in a dry, sheltered place in closed bags. 
Packing is 25 Kg net paper bags on wood pallets of 1,000 - 1,400 Kg each.
