WorléeDur D 46
High-quality zinc dust and rust protection paints, air-drying and oven-drying base and top coats, quick-drying and waterproof
Compatibility
WorléeDur D 46 is compatible with unplasticized urea and melamine formaldehyde resins, with the short-oil alkyd resin WorléeKyd L 138, MH 38 and with the phenolic modified rosin esters WorléeFen F 105 and F 130. It is partially compatible with WorléeKyd T 730 and SM 400.
Solubility
WorléeDur D 46 is readily soluble in aromatic solvents, esters, ketones and glycol ethers. It has limited solubility in higher alcohols, and is insoluble in aliphatic solvents and lower alcohols.
Application and properties
WorléeDur D 46 is an excellent binder for quick-drying primers and top-coats with very good adhesion and chemical resistance. Zinc-rich primers based on WorléeDur D 46 have very good stability and anticorrosive properties. WorléeDur D 46 is also used as a binder for screen printing inks with good adhesion on a variety of plastic substrates.
The addition of WorléeDur D 46 to air-drying zinc chromate primers based on WorléeKyd L 138 or MH 38 improves the adhesion, corrosion and alkali resistance. WorléeDur D 46 is also used in combination with unplasticized amino resins for high quality stoving primers and top-coats for washing machines and similar applications.
In combination with reactive melamine resins a mixing ratio of 80:20 – 90:10. and with reactive urea resins 70:30 – 80:20 (calculated on solids content) is recommended. The best stoving temperature is 120-140 °C.
Driers
The following driers are recommended for WorléeDur D 46:
0.01 – 0.02% Co
0.05 – 0.10% Ca
