BECKOCURE EH 2260W/41WA

BECKOCURE EH 2260W/41WA is an 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 behaviour and a very robust performance even on poorly prepared surfaces. 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.
BECKOPOX EP 147W

BECKOPOX EP 147W is a non-crystallizing, contains co-reacting emulsifiers. Primers/coatings on mineral and metallic substrates. Adhesives and water-washable jointing-compounds for tiles. BECKOPOX EP 147W is a non-crystallizing Bisphenol A/F liquid epoxy resin containing cross-linkable emulsifiers. Formulations cured with Beckopox EH 613w, EH 623w or EH 659w give hard films with high abrasion resistance, good corrosion protection and chemical resistance. To adjust viscosity a reduction with reactive diluents such as Beckopox EP 075 and EP 080 is possible. Beckopox EP 147w can be formulated together with the solid resin dispersions Beckopox EP 384w or EP 385w to improve their hardness adhesion to porous substrates.
BECKOPOX EP 387W/52WA

BECKOPOX EP 387W/52WA is an internally plasticized solid resin-Type 1-dispersion with improved shear stability, e. g. for water reducible fast drying anticorrosion primers and coatings for plastics.BECKOPOX EP 387W/52WA is an internally plasticized type 1solid epoxy resin as aqueous dispersion. Formulated together with adequate curing agents such as e. g. Beckopox VEH 2188w/55WA it is suited for corrosion protection primers with very good adhesion to most metallic substrates. It is also suitable for use in single coat and decorative systems for metallic substrates. For optimium corrosion protection it is recommended using 75 % of the stoichiometric curing agent quantity. Dispersion of pigments and fillers can be done in Beckopox EP 387w/52WA if the temperature does not exceed 40 °C. The formulated paint stability can be influenced by the additives used so that it is important to investigate their suitability thoroughly; such additves should not contain functional groups capable of reacting with epoxy groups.
CYCAT XK 406 N

CYCAT XK 406 N is a phosphoric acid derivate. CYCAT XK 406 N increases the crosslinking speed of heat curing coating systems based on e.g. phenolic/‐epoxide resin combinations. A significant improvement of adhesion properties is often seen in connection with the use of CYCAT XK 406 N. Furthermore, the use of CYCAT XK 406 N often leads to an improved sulphur staining resistance of interior can coating systems based on phenolic/epoxide resin combinations.
