ARGIMEL® ED

LAVIOSA ARGIMEL® ED Rheological Additive for Solvent Borne Paint and Coatings

Industrial Additives Division Coatings

General Information

LAVIOSA 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 LAVIOSA ARGIMEL® ED is a bentonite clay organically modified with a quaternary alkylammonium compound.

Properties
Composition: Organically modified smectite
Physical form: White fine powder
Bulk density: 0.4-0.6%
Moisture: < 3%

Applications

LAVIOSA 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

For architectural paints production, anticorrosive paints, road marking paints, primers, bituminous emulsions, and wood paints. LAVIOSA 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 LAVIOSA ARGIMEL® ED.

Incorporation

LAVIOSA ARGIMEL® ED belongs to the unconventional type of self-activating organoclays. It 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. It 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 LAVIOSA ARGIMEL® ED is added under low shear. Pre-gel formation is not needed to employ LAVIOSA ARGIMEL® ED and in order to develop its full rheological properties.

Dosage

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 LAVIOSA ARGIMEL® ED. For primers and printing inks, higher levels are required (0.5-1.0%). For strong anti-sagging properties, up to 3.0% can be used.

Storage Stability and Packing

Storage is advisable in a dry sheltered place in closed bags. LAVIOSA ARGIMEL® ED rheological additive is available in 25 kg net paper bags. LAVIOSA ARGIMEL® ED has a shelf life of 3 (three) years from the date of manufacture.
