ROSKYDAL XP 2072 is especially suitable for conventional- or UV-curing (transparent or pigmented) topcoats and pigmented sealers for wood and furniture. properties for applications by spraying or curtain in UV- or conventionalcuringsystems. ROSKYDAL XP 2072 is usually used as the sole binder. If made necessary by the application (high amount) and compatibility exists, it can be flexibilized with other ROSKYDAL grades, e.g. ROSKYDAL 550 or E 70.

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 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.

BECKOCOAT PU 428/51XMPAC is a rapid curing. Radiant brilliance. Superior abrasion resistance. Outstanding impact resistance, excellent adhesion. Floor sealers, wood coating, concrete impregnation. Crosslinker for alkyd resins in two-component systems.The extreme abrasion resistance, impact resistance, and chemical resistance make Beckocoat PU 428 films cured with the action of air humidity an excellent sealer and impregnation medium for concrete, a binder for non-slip coatings, for concrete coatings resistant to fuel oil and abrasion, for instance in garages, or for floorings and coatings for walls and ceilings in laboratories, chemical factories, etc. The films cure to radiant brilliance and can also be recommended for wooden floors subject to heavy wear like in bowling alleys, roller skating rinks, dancing halls, gymnasiums and schools. Beckocoat PU 428 has also proved an ideal vehicle for coating sports articles like spears, bowling pins, golf balls, bats, hockey sticks, tennis rackets, etc. In exterior use, Beckocoat PU 428 will lose gloss and will yellow. Weather resistance and gloss retention can be enhanced through coemploying alkyd resins like VIALKYD AR 408.
