Applications

LAVIOSA VISCOGEL™ S8 is used in a wide range of manufacturing processes of industrial paints, anticorrosive paints, automotive finishes primers, coil coatings, architectural paints, primers, cosmetics, adhesive and mastic compound, to give the desired rheological control to the system. It shows particularly good performance in aromatic and alyphatic solvents and resins like alkyds, epoxy esters, polyacrylics, polyesters and polyurethanes.

INCORPORATION

LAVIOSA VISCOGEL™ S8 belongs to the conventional type of organoclays group, which requires mechanical energy, shear forces applied with a good dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organobentonite platelet stacks.

Several methods can be used to incorporate LAVIOSA VISCOGEL™ S8:

1. The “direct add” technique. LAVIOSA VISCOGEL™ S8 is added directly in powder form to the solvent/resin mix, before pigment addition and milling. Surfactants have to be added the last.

2. The “pregel” technique. LAVIOSA VISCOGEL™ S8 is pregelled as described above in a suitable solvent at a 5-10 % concentration, with a polar activator. The activated gel is then added to the binder solution and stirred. After pigment addition the mix is finally milled.

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 0.6 % of LAVIOSA VISCOGEL™ S8. For primers and printing inks, higher levels are required (0.5-1.0 %). For strong antisagging properties, up to 3.0 % can be used.

Storage is advisable in a dry, sheltered place in closed bags. Packing is 20 Kg net paper bags on wood pallets of 1,000 - 1,400 Kg each.
