BECKOPOX EP 386W/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 386W/52WA is an internally plasticized type 1solid epoxy resin as aqueous dispersion. Formulated together with adequate curing agents such as e. g. Beckopox EH 613w or VEH 2188w 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 80 % of the stoichiometric curing agent not contain functional groups capable of reacting with epoxy groups.

BECKOPOX EH 623W/80WA is a hardener for water-reducible coatings on mineral and metallic substrates, hydryaulic epoxy mortars (ECC). BECKOPOX EH 623W/80WA is used in combination with the water emulsifiable liquid resins Beckopox EP 122w, EP 147w and other liquid resins such as Beckopox EP 140, EP 116 and the solid resin dispersions Beckopox EP 384w and EP 385w (preferably in combination with liquid EP-resins) to produce water-thinnable paints hardening at room temperature with good adhesion to all mineral substrates.Drying at elevated temperatures (> 60 °C) should be avoided. At such conditions traces of acrylonitrile will be released. If the hardener is diluted with water there may be stability problems at solid concentrations of less than 20 %, especially at storage temperatures above 35 °C. When pigments and fillers are being dispersed in the hardener, the temperature must not be allowed to rise above 40 °C. These paints retain a constant gloss irrespective of thinning ratio or the time between mixing and the end of the pot life. Beckopox EH 623w may be used in combination with Beckopox EP 128 as an additive for hydraulic mortars, the mechanical properties of the cured system being considerably enhanced by the additive.

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.
