WorléeKyd C 641

WorléeKyd C 641 is an extremely low viscous alkyd resin based on saturated fatty acids. It's designed for combination with nitrocellulose, suitable for clear and pigmented nitrocellulose lacquers, as well as one-component acid-curing coatings for wood, foil, and paper. Here are its technical specifications:

• Oil content: Approximately 42%
• Content of phthalic anhydride: Approximately 32%
• Non-volatile content, 1h/125 °C: 70% ± 1 (DIN EN ISO 3251)
• Colour (Gardner), 50% in xylene: Maximum 10 (DIN ISO 4630)
• Acid value, on solids: Maximum 15 (DIN EN ISO 3682)
• Flow time, 20 °C, 50% in xylene: 24 - 30 seconds (DIN 53211-4)
• Delivery form: 70% in xylene

WorléeKyd C 641 is completely compatible with most short oil alkyds, unmodified urea formaldehyde and melamine resins, nitrocellulose, plasticizers, and maleic resins. Its solubility characteristics include complete solubility in aromatics, esters, and ketones, and partial solubility in aliphatics, glycol ethers, and low alcohols.

Applications and properties:

• Particularly used for high-quality clear and pigmented nitrocellulose lacquers.
• Features very quick solvent release, good recoatability at any time, and excellent yellowing resistance.
• The extremely low viscosity of WorléeKyd C 641 guarantees nitrocellulose lacquers with high film build and very good gloss.
• Sanding sealers based on a ratio of 2:1 (calculated on solids content) of WorléeKyd C 641 and nitrocellulose dry very quickly and have good sanding properties.
• It's also used in combination with nitrocellulose, plasticizers, and unmodified urea resins, catalyzed with acid, for one-pack acid-curing coatings.
