SETAQUA 6160 is an acrylic polyol emulsion is developed for waterborne solid colour topcoat (1 coat - 1 bake) and is used in combination with partly methylated melamine resins. SETAQUA 6160 gives high gloss coatings having excellent chemical resistance and durability. It is used as waterborne solid colour topcoat.

SETAQUA B E 270 is applied in combination with water-thinnable amino resins in the formulation of industrial stoving coatings and aqueous stoving primer surfacers for online automotive finishing, both with a low co-solvent content. Combined with water-thinnable amino resins. SETAQUA B E 270 is particularly suitable for the formulation of aqueous stoving primer surfacers with low cosolvent content for use in online automotive finishing. To ensure good intercoat adhesion to conventional automotive topcoats, a SETAQUA- /amino resin ratio of 90:10 to 85:15 (calculated on the solvent-free resin) is recommended. The paint films yielded have good hardness, flexibility and adhesion. If above-average stonechip resistance is required, SETAQUA B E 270 should be combined with polyurethane dispersions. SETAQUA B E 270 can also be used in general industrial finishing. Depending on the reactivity of the melamine resin used, a ratio of 85:15 to 70:30 can be used to formulate highly flexible primers and hard, well crosslinked, high gloss top coats. SETAQUA B E 270 has proved particularly suitable for the formulation of dip primers which are subsequently overcoated with Powder Coating. The stoving conditions for SETAQUA B E 270 depend on the type of amino resin used. The stoving range is between 30 min. at 120 °C and 60 min at 180 °C in the overbaking process. Because of the good shear stability of SETAQUA B E 270, the pigments can be added directly to the binder. Suitable grinding equipment includes the bead mill, dyno mill and red devil. However, the use of suitable wetting agents and antifoams is essential. Optimum pigment wetting is achieved if the entire amount of dimethyl ethanol amine required to adjust the coating to a pH of 8.5 - 8.8 is added to the mill base. Details are given in the guide formulations for SETAQUA B E 270.

SETAQUA ECO 6794 is a fine particle size, self-crosslinking acrylic dispersion with improved low temperature flexibility, combined with good flow and levelling properties and with good block and chemical resistance. It is used as decorative trim paints for interior and exterior applications. Air-drying exterior pigmented and non pigmented wood finishes for the joinery industry.

SETAQUA 6802 is a pseudoplastic after neutralization, good aluminium orientation, good atomisation, insoluble in organic solvents, excellent stability. It is used as metallic and solid colour waterborne base coats for the automotive OEM industry.
