SIGMAGUARD CSF 650 6 pages DESCRIPTION April 2009 Revision of November 2008 two component solvent free amine cured epoxy coating PRINCIPAL CHARACTERISTICS – – – – – – – – – – – tank coating for crude oil/ballast and aliphatic petroleum products also suitable as coating system for storage and transport of drinking water good resistance to various chemicals one coat protection for steel structures, ships and storage tanks with excellent corrosion resistance can be applied by heavy duty single feed airless spray equipment (60:1) reduced explosion risk and re hazard good visibility due to light colour also a conductive version is available, see sheet 7753 can be reinforced with chopped glassbre or mat clear version for glassmat reinforced solvent free tank bottom system (see system sheet 4144) meets the requirements of Mil-C-4556E concerning resistance against aircraft fuel and fuel degradation COLOURS AND GLOSS green, offwhite, clear - gloss 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) Mass density Volume solids VOC (supplied) 1.3 g/cm³ 100% max. 109 g/kg (Directive 1999/13/EC, SED) max. 143 g/l (approx. 1.2 lb/gal) see information sheet 1411 300 - 600 µm depending on system 3.3 m²/l for 300 µm * 8 hours min. 24 hours * max. 20 days * 5 days * 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 – steel; blast cleaned to ISO-Sa2½, blasting prole 50 - 100 µm – suitable primer; SigmaGuard 260, SigmaCover 280, SigmaPrime series or SigmaCover 522, depending on system requirements – substrate temperature must be above 5°C and at least 3°C above dew point during application and curing SYSTEM SPECIFICATION marine or suitable primer (min. dft of 50 µm) + page 1/6 1 x 300 µm SigmaGuard CSF 650 1 x 250 µm SigmaGuard CSF 650

SIGMAGUARD CSF 650 April 2009 INSTRUCTIONS FOR USE mixing ratio by volume: base to hardener 80 : 20 – the temperature of the mixed base and hardener should preferably be above 20°C – at lower temperature the viscosity will be too high for spray application – no thinner should be added – for recommended application instructions: see working procedure Induction time none Pot life approx. 1 hour at 20°C * * see additional data AIRLESS SPRAY Recommended thinner Nozzle orice Nozzle pressure – use heavy duty single feed airless spray equipment preferably 60:1 pump ratio and suitable high pressure...

SIGMAGUARD CSF 650 April 2009 ADDITIONAL DATA Film thickness and spreading rate theoretical spreading rate m²/l 4.0 3.3 1.7 dft in µm 250 300 600 max. dft when brushing: 150 - 200 µm measuring wet lm thickness – a deviation is often obtained between the measured apparent wft and the real applied wft – this is due to the thixotropy and the surface tension of the paint which retards the release of air trapped in the paint lm for some time – recommendation is to apply a wft which is equal to the specied dft plus 60 µm measuring dry lm thickness – because of low initial hardness the dft cannot...

SIGMAGUARD CSF 650 April 2009 – when used as coating system for storage and transport of drinking water the recommended working and washing procedure should be followed WASHING PROCEDURE The recommended washing procedure must be applied after completion of the application. Sufcient time for full-curing and ventilation must be allowed in accordance with the recommendations as stated in the latest Product Data Sheets and working procedure. Always an adequate washing procedure should be followed. Several adequate washing procedures are available and may be used (see e.g. washing procedure...
