VISCOGEL XD

VISCOGEL XD is a new high performing, highly effective rheological additive for solvent-borne systems of low to medium polarity.
That provides thixotropic effect, sag control, excellent levelling and prevents pigments from long-term storage settling.

The nature of VISCOGEL XD is a highly purified bentonite clay, organically modified with a quaternary alkylammonium compound. 
Unlike most of the other conventional organoclays, VISCOGEL XD is self-activating and easily dispersible, hence simple and convenient to use.

VISCOGEL XD is a highly effective, self-activating, easy dispersible, highly purified, bentonite clay, organically modified with quaternary alkylammonium compound. 
VISCOGEL XD is acts as a rheology modifier. 

VISCOGEL XD is offers thixotropic effect, sag control and excellent levelling. 
VISCOGEL XD prevents pigments for long-term pigment storage settling. 

VISCOGEL XD is compatible with low polarity binders like alkyds and terpenes, petroleum derivatives and styrene-butadiene rubbers. 
VISCOGEL XD is designed for solvent borne systems of low to medium polarity. 

VISCOGEL XD is used for architectural paints, industrial finishes, anti-corrosive paints, road marking paints, primers, bituminous undercoats and wood stains. 
VISCOGEL XD is recommended applications include house & industrial paints (at dosage level 0.2% - 0.8%), primers & printing inks (at dosage level 0.5% - 1.0%), and for applications with strong anti-sagging properties (at dosage level up to 3.0%). 

VISCOGEL XD shows good compatibility with low polarity binders like alkyds & terpenes, petroleum derivatives and styrene-butadiene rubbers. 
VISCOGEL XD is used in recommended for applications with strong anti-sagging properties (at dosage level up to 3.0%). 

VISCOGEL XD is complies with ISO 9001 regulation. 
The shelf life of VISCOGEL XD is 36 months.

VISCOGEL is essential additives in the formulation of printing inks to adjust their rheological properties, especially in high-speed printing inks. 
The use of VISCOGEL contributes to flow, obtaining an even consistency and better printing resolution. 

VISCOGEL is frequently used in lithographic inks, for newspapers and letterheads.
The range we offer includes a vast number of available VISCOGEL. 

There are two methods of incorporation:
The conventional method requiring the formation of a “pregel” with a polar activator, or direct addition of the product in dispersible form, for which a polar activator is not required.
VISCOGEL XD is a new high performing, highlyeffective rheological additive for solvent-bornesystems of low to medium polarity.

Dosage of VISCOGEL XD:
Level of addition strongly depends on the type of system and on the degree of thickening or other properties desired. 
For house and industrial paints, typical levels are between 0.2 % and 0.8 % of VISCOGEL XD. 

For primers and printing inks, higher levels are required (0.5-1.0 %). 
For strong antisagging properties, up to 3.0 % can be used.
Compared to other products of its type VISCOGEL XD is also proved to be more versatile in terms of compatibility to a wide range of formulations.

Applications of VISCOGEL XD:
VISCOGEL XD is used in a wide range of manufacturing processes for architectural paints, industrial finishes, anti-corrosive paints, road marking paints, primers, bituminous undercoates, wood stains, to give the desired rheological control to the system. 
VISCOGEL XD provides superior antisettling anti anti-sagging and VISCOGEL XD shows also a very high dispersibility.

VISCOGEL XD shows particularly good performance in aliphatic mineral spirits and aromatics. 
Low polarity binders like alkyds and terpenes, petroleum derivatives and styrenebutadiene rubbers are also compatible with VISCOGEL XD.

VISCOGEL XD belongs to the unconventional type of organoclays group, being an easy-todisperse, self-activating, organobentonite.
VISCOGEL XD does not require neither strong mechanical energy to disperse nor a chemical (polar) activator to reach the proper level of delamination of the organobentonite platelet stacks.

VISCOGEL XD can be added at any point in the paint manufacturing process and can be even used in post-addition to correct the final viscosity of a certain batch.
Low temperature might be a cause of slow dispersion if VISCOGEL XD is added under low shear.

VISCOGEL XD does not need to be pregelled to develop VISCOGEL XD full rheological properties. 
If however a pregel is convenient to be produced, this won’t show the same high viscosity of a conventional organoclay activated gel. 
VISCOGEL XD is not effective as a gellant in a solvent alone, but VISCOGEL XD provides the same rheological properties when added to the complete system. 

Storage Stability and Packing of VISCOGEL XD:
VISCOGEL XD 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 - 1,300 Kg each.
