SETAQUA® B E 270 Features & Benefits

Applications & Uses

Recommended Uses & Known Applications


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 coatings.
  • 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.

6 Months
Storage and Handling
  • When stored in originally sealed containers at temperatures not exceeding 30°C, the product will remain stable for 6 months. In tank-containers the product will only remain stable for at least 270 days.
  • General information: The product is sensitive to frost. Freezing will damage the product irreversibly. Prolonged storage and storage at higher temperatures may result in a decrease of viscosity and/or an increase of average particle size, possibly resulting in sedimentation or coagulation. Contamination with certain bacteria, fungi or algae may render the product unusable.
