SYNRESIN NDC - 35
Short oil, penta esterified alkyd resin, modified with castor oil.
Principal properties
Very good compatibility with nitro cellulose lacquers. In stoving enamels; rapid curing, high gloss, good adhesion on light metals. In nitro cellulose lacquers very good hardness, good yellowing resistance.
Applications
Stoving enamels for steel furniture and drums. Nitro cellulose polishing lacquers for furniture.
