W´Kyd C 641
W´Kyd C 641 is an extremely low viscous alkyd resin based on saturated fatty acids for the combination with nitrocellulose, for clear and pigmented nitrocellulose lacquers and onecomp. acid curing coatings for wood, foil and paper.
W´Kyd V 5241 U is a low viscosity linseed oil based urethane alkyd resin.
W´Kyd C 641 is especially used for high quality clear and pigmented nitrocellulose lacquers. The technical features are: very quick solvent release, good recoatability at any time and very good yellowing resistance. The extremely low viscosity of W´Kyd C 641 guarantees nitrocellulose lacquers with high film build and very good gloss.
Sanding sealers based on W´Kyd C 641 and nitrocellulose in the ratio 2:1 (calculated on solids content) dry very quickly and have good sanding properties.
W´Kyd C 641 is also used in combination with nitrocellulose, plasticizers and unmodified urea resins, catalysed with acid, for one-pack acid curing coatings.
