Special Features and Benefits
DISPERBYK® 2151 is recommended for use in solvent-borne and solvent-free epoxy systems and other reactive systems such as acid-catalyzed systems and two-pack polyurethanes. During the grinding of the pigments and fillers, the polyester side chains of the additive are compressed and the adhesive forces of the aminic group toward the pigment and fi ller surface are increased. The pigment-affi nic group is then adsorbed onto the pigments and fi llers, while the polyester side chains still shield the aminic group from the epoxy resin. This
results in a signifi cant reduction in viscosity, also in solvent-free formulations, and no undesirable interactions with the binder; thereby achieving a long-term storage stability. The wetting and defl occulation of solids is outstanding. DISPERBYK® 2151 is broadly compatible and has no negative infl uence on corrosion resistance, yellowing resistance and adhesion to metal.Recommended Levels
Amount of additive (as supplied) based upon pigment:
Inorganic pigments: 5-10 %
Titanium dioxides: 1-3 %
Organic pigments: 20-45 %
Carbon blacks: 20-80 %
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
For optimum performance, the additive must be incorporated into the millbase before addition of pigments. Pre-mix the resin and solvent components of the millbase and then gradually let the DISPERBYK® 2151 flow in whilst stirring. Only add the pigments when the additive has been thoroughly distributed.
