SIGMADUR 580 (SIGMADUR HS SEMIGLOSS) 4 pages DESCRIPTION September 2010 Revision of April 2007 two component high solids semigloss recoatable acrylic polyurethane nish PRINCIPAL CHARACTERISTICS – – – – – – excellent resistance against corrosion and sea water excellent colour and gloss retention non-chalking, non-yellowing cures at temperatures down to -5°C tough and abrasion resistant resistant to splash of mineral and vegetable oils, parafns, aliphatic petroleum products and mild chemicals – can be recoated even after long atmospheric exposure – lead- and chromate free COLOURS AND GLOSS white (other colours on request) - semigloss BASIC DATA AT 20°C (1 g/cm³ = 8.25 lb/US gal; 1 m²/l = 40.7 ft²/US gal) (data for mixed product) 1.4 g/cm³ 75 ± 2% max. 191 g/kg (Directive 1999/13/EC, SED) max. 269 g/l (approx. 2.2 lb/gal) 75 μm depending on system 10 m²/l for 75 μm * 2 hours min. 12 hours * max. unlimited 7 days * Mass density Volume solids VOC (supplied) Recommended dry lm thickness Theoretical spreading rate Touch dry after Overcoating interval Full cure after (data for components) Shelf life (cool and dry place) at least 12 months * see additional data RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES – previous coat; (epoxy or polyurethane) dry and free from any contamination and sufciently roughened if necessary – substrate temperature should be at least 3°C above dew point – maximum relative humidity during application and curing is 85% INSTRUCTIONS FOR USE mixing ratio by volume: base to hardener 82 : 18 – the temperature of the mixed base and hardener should preferably be above 15°C, otherwise extra solvent may be required to obtain application viscosity – too much solvent results in reduced sag resistance – thinner should be added after mixing the components Pot life 5 hours at 20°C * * see additional data page 1/4
