High-performance hydrophobic copolymer dispersant especially suitable for semi-gloss and gloss paints. Supplied in an emulsion form, manufactured without the use APEO surfactants(1). Relative to OROTAN™ 681 Dispersant, OROTAN™ 2002 Dispersant offers reduced use cost, reduced as-supplied viscosity, lower odor, higher as-supplied solids, and formulation flexibility via choice of neutralizing base and absence of solvent. Supplied in the un-neutralized emulsion form and thus, allows the formulator to choose the neutralizing base to best meet odor and handling requirements. Sodium hydroxide, potassium hydroxide, sodium carbonate and AMP™ 95 Multifunctional Amine, as well as ammonia, can be used to neutralize the emulsion. Depending on the formulation, improved gloss and reduced silking compared to OROTAN™ 681 Dispersant has been seen in laboratory testing. Similar to OROTAN™ 681 Dispersant, OROTAN™ 2002 Dispersant offers excellent gloss potential combined with good corrosion resistance and compatibility with reactive pigments. It is very compatible with HEUR rheology modifiers. Early water resistance is strongly influenced by the choice of neutralizing base, with volatile bases typically giving better resistance.
