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 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 EM 2120W/45WA is an epoxy-amine-adduct dispersion in water, containing very small amounts of organic co-solvent. Beckopox EM 2120w is suited to formulate water borne 1 pack anticorrosive primers and 1 pack single coats with good anticorrosive properties, especially on smooth steel. Due to the special character of Beckopox EM 2120w very fast drying coatings can be formulated. Pigments and extenders should be dispersed in a pigment paste since Beckopox EM 2120w does not possess sufficient shear stability. Organic solvents in the formulation should be added to the pigment paste or should be diluted with water before adding to EM 2120.

EPOXY NPEF 180 is a Bisphenol F epoxy resin blended with Bisphenol A epoxy resin. The low viscosity allows high filler loading and gives good wetting effect. NPEF-180 can be blended with common epoxy resins. Cured with polyamines or polyamides at ambient condition, it provides good levels of chemical resistance and physical properties.
