ARGIMEL® ED2

LAVIOSA ARGIMEL® ED2 is a new high performing highly effective rheological additive for solvent-borne systems of moderate to high polarity that gives excellent thixotropic effect, sag control, leveling, and prevents pigments from long-term storage settling. The nature of LAVIOSA ARGIMEL® ED2 is a highly purified bentonite clay organically modified with a quaternary alkylammonium compound. Unlike most conventional organoclays, LAVIOSA ARGIMEL® ED2 is self-activating and easily dispersible, hence simple and convenient to use.

Applications

LAVIOSA ARGIMEL® ED2 is used in a wide range of manufacturing processes including anti-corrosive paints, industrial finishes, anti-fouling paints, printing inks, cosmetics, adhesives, and mastics to give the desired rheological control to the system. It provides superior anti-settling and anti-sagging properties and shows particularly good performance in aromatics, Cellosolve™ acetates, ketones, glycols, alcohols, and resins like epoxies, nitrocellulose, polyacrylates, polyesters, polyurethanes, and polyvinyls.

Incorporation

LAVIOSA ARGIMEL® ED2 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 platelets. LAVIOSA ARGIMEL® ED2 can be added at any point in the paint manufacturing process and can even be used in post-addition to correct the final viscosity of a certain batch.

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® ED2. 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® ED2 rheological additive is available in 20 kg net paper bags. LAVIOSA ARGIMEL® ED2 has a shelf life of 3 (three) years from the date of manufacture.
