LAVIOSA 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. It provides superior anti-settling anti anti-sagging and it shows also a very high dispersibility. LAVIOSA 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 LAVIOSA VISCOGEL™ XD.
Incorporation
LAVIOSA VISCOGEL™ XD belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activating, organobentonite. Laviosa 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. LAVIOSA 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 LAVIOSA VISCOGEL™ XD is added under low shear. LAVIOSA VISCOGEL™ XD does not need to be pregelled to develop its 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. LAVIOSA VISCOGEL™ XD is not effective as a gellant in a solvent alone, but it provides the same rheological properties when added to the complete system.
- Dosage and Storage Stability
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 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 it is also proved to be more versatile in terms of compatibility to a wide range of formulations.
