Distinguishing Features

BECKOCURE® EH 2260w is more reactive than BECKOPOX™ EH 2188 and provides a much better anticorrosion protection than BECKOPOX™ EH 613. Especially in combination with BECKOPOX™ EP 2384 very fast drying anticorrosion Primers and Monocoats can be formulated.

Applications & Uses

Compatible Substrates & Surfaces
Special Properties and Uses

Hydrophobic amine hardener especially for the formulation of waterborne metal coatings, free of volatile basic amines and solvents. In combination with epoxy dispersions fast drying Primers and Monocoats with excellent corrosion protection and very good non-sagging properties can be formulated. The product shows excellent application behavior and a very robust performance even on poorly prepared surfaces.

Suggested Uses and Processing Information
  • BECKOCURE® EH 2260w is used together with solid epoxy resin dispersions or emulsified liquid resins. Best results are obtained using 50 - 75% of the stoichiometric amount of hardener. The films cure rapidly at room temperature but can also be dried at elevated temperatures.
  • Grinding of the pigments can be done in BECKOCURE® EH 2260w or as well in shear stable epoxy dispersions (e. g.: BECKOPOX™ EP 2384w, BECKOPOX™ EP 386, BECKOPOX™ EP 387 or BECKOPOX™ VEP 2381w). The mill base temperature should not exceed 40°C. The use of binder-free pigment pastes is recommended when the grinding temperature cannot be controlled. Dilution can be done with BECKOCURE® EH 2260w or an epoxy dispersion.

MIXING RATIO AND POT LIFE

A blend of 75.0 g BECKOPOX™ EP 2384w/57WA 100.0 g BECKOCURE® EH 2260w/41WA 12.0 g deionized water (=100% of the stoichiometric amount of hardener) has a processing time of approx. 60 minutes at 23°C. The end of pot life cannot be seen by a sharp increase of viscosity or gelation. Therefeore it is necessary to use the paint within the stated time limit. Addition of coalescing solvents can elongate the usable time.
