ARGIMEL ED

Argimel ED is used in primers, anti-corrosive coatings, metal coatings, road-marking paints, and wood coatings to prevent pigment settling, reduce sagging on vertical surfaces, and ensure uniform film thickness.
Argimel ED is also commonly used in printing inks, where it helps maintain pigment suspension and improves printing consistency at high speeds.

Argimel ED is a self-activating and easily dispersible rheological additive for solvent-borne systems from low to medium polarity that gives thixotropic effect, sag control, and prevents pigments from long-term storage settling.
The nature of Argimel ED is a bentonite clay organically modified with a quaternary alkylammonium compound.

Argimel ED is a self-activating and easily dispersible rheological additive.
Argimel organoclays are rheology modifiers that provide controllable thixotropy, ie thickening, anti-settling, flow, levelling and anti-sagging.

USES and APPLICATIONS of ARGIMEL ED:
In terms of uses and applications, Argimel ED is widely applied in the paints and coatings industry, especially in solvent-based architectural and industrial coatings.
Argimel ED is used in primers, anti-corrosive coatings, metal coatings, road-marking paints, and wood coatings to prevent pigment settling, reduce sagging on vertical surfaces, and ensure uniform film thickness.

Argimel ED is also commonly used in printing inks, where it helps maintain pigment suspension and improves printing consistency at high speeds.
In addition, Argimel ED finds application in bituminous coatings, sealers, and specialty industrial formulations, as well as in certain lubricants and grease systems where rheology control is required.

Argimel ED 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.
Argimel ED belongs to the unconventional type of self-activating organoclays.

Argimel ED does not require strong mechanical energy to disperse nor a chemical (polar) activator to reach the proper level of delamination of the organo-bentonite platelet stacks.
Low temperature might be a cause of slow dispersion if Argimel ED is added under low shear.

Pre-gel formation is not needed to employ Argimel ED and in order to develop its full rheological properties.
Argimel ED is used for architectural paints production, anticorrosive paints, road marking paints, primers, bituminous emulsions, and wood paints.

Argimel ED shows good performance in solvents like aliphatic mineral spirits and aromatic solvents.
Low polarity binders like alkyds and terpenes petroleum derivatives are also compatible with Argimel ED.
Argimel ED is employed in a wide range of manufacturing processes: Oil-based paints (either industrial or architectural), Marking paints, Road marking paints, Wood paints, Primers, Bituminous, Adhesives, Cosmetics and personal care products.

Usage Rate of Argimel ED: Typically between 0.2% and 1.0%, up to 3% in systems requiring intensive salivation monitoring.
Areas of Application of Argimel ED: Architectural and industrial paints, Road marking paints, Bitumen-based primers, Wood stains, Printing inks (especially lithographic and letterpress), Oil and grease formulations (viscosity enhancers, stability improvers).

Argimel ED is used in oil based paints (either industrial or architectural), anti-corrosive paints, road marking paints, primers, bituminous emulsions and wood paints.
Recommended dosage level of Argimel ED is 0.2-0.8% for paints & industrial finishes, 0.5-1.0% for primers & printing inks and upto 3.0% for anti-sagging properties.

BENEFITS of ARGIMEL ED:
The benefits of Argimel ED are closely related to its ability to improve both processing and final performance.
Argimel ED provides excellent anti-settling and anti-sag properties, ensuring that pigments and fillers remain evenly distributed during storage and application.
This results in better appearance, consistent color, and uniform coating thickness.

Argimel ED also enhances application control, making coatings easier to apply on vertical or inclined surfaces without dripping or running.
Argimel ED's thixotropic behavior improves leveling and surface smoothness, contributing to a higher-quality finish.
Another key benefit is Argimel ED's ease of incorporation; as a self-activating organoclay, it requires less mechanical energy and fewer activators compared to traditional organoclays, simplifying formulation and processing.

FUNCTIONS of ARGIMEL ED:
Argimel ED provides thixotropy.
Argimel ED performs a flow (right) check.
Argimel ED prevents pigments from settling.
Argimel ED improves surface leveling.

KEY FEATURES of ARGIMEL ED:
Argimel ED is a self-activating and easily dispersible additive.
This means Argimel ED doesn't require high energy or special activators.
