SIGMAGUARD CSF 650 SIGMA TANK COATING
GZ Industrial Supplies is a distributor of Sigma Marine coatings in Nigeria, SIGMAGUARD CSF 650 SIGMA TANK COATING is a two-component, solvent-free, amine-cured epoxy coating, used primarily for tank coating of crude oil ballast or aliphatic products, it is a chemical resistant tank lining. After application it is highly glossy, color is Green, off white and clear
PRODUCT CHARACTERISTICS OF SIGMAGUARD CSF 650 SIGMA TANK COATING
- Tank coating for crude oil/ballast and aliphatic petroleum products
- Also suitable as a coating system for the storage and transportation 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 fire hazard
- Good visibility due to light color
- Also, a conductive version is available ; SigmaGuard CSF 660
- Can be reinforced with chopped glass fiber or mat
- Clear version for glass-mat reinforced, solvent-free tank bottom system (see SYSTEM SHEET 4144)
- Meets the requirements of EI 1541 (coating systems for aviation fuel storage tanks and pipes)
- Excellent resistance to crude oil up to 60°C (140°F)
RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES
Substrate conditions
Substrate temperature and application conditions.
- Steel; power tooling to ISO-St3 for small and isolated areas (like repairs and joint welds) in fresh water and potable water tanks where spot blasting might be impractical
- Substrate temperature during application and curing should be above 5°C (41°F)
- Substrate temperature during application should be at least 3°C (5°F) above dew point
SYSTEM SPECIFICATION
SIGMAGUARD CSF 650: 1 x 300 μm (12.0 mils); or a suitable primer of 50 μm (2.0 mils) + SIGMAGUARD CSF 650: 1 x 250 μm (10.0 mils)
INSTRUCTIONS FOR USE
Mixing ratio by volume: base to hardener 80:20 (4:1)
- At lower temperature, the viscosity will be too high for spray application
- For recommended application instructions, see working procedure
- The temperature of the mixed base and hardener should preferably be above 20°C (68°F)
- No thinner should be added
Airless spray
- Use heavy-duty, single-feed, airless spray equipment, preferably 60:1 pump ratio and suitable high-pressure hoses/in- line heating or insulated hoses may be necessary to avoid cooling down of paint in hoses at low air temperature
- Application with 45:1 airless spray equipment is possible, provided in-line, heated high-pressure hoses are used
- Length of hoses should be as short as possible
Recommended thinner
No thinner should be added
Nozzle orifice
Approx. 0.64 mm (0.025 in)
Nozzle pressure
At 20°C (68°F) paint temperature min. 28.0 MPa (approx. 280 bar; 4061 p.s.i.). At 30°C (86°F) min. 22.0 MPa (approx. 220 bar; 3191 p.s.i.)
Note: In case of using 45:1 airless spray equipment, the paint must be heated to approximately 30°C (86°F) in order to obtain the right application viscosity
Brush/roller
Recommended thinner
For stripe coating and spot repair only, no thinner should be added
Cleaning solvent
THINNER 90-53 or THINNER 90-83

Frequently Asked Questions
1. Can I use regular paint instead of marine paint on my boat?
Regular paint is not recommended for use on boats as it does not provide the necessary protection against marine-specific challenges such as corrosion, UV exposure, and fouling. Marine paint is formulated with specialised ingredients to withstand the unique conditions of the marine environment.
2. Can I apply marine paint myself, or do I need a professional?
Applying marine paint can be done by boat owners themselves. However, proper surface preparation and application techniques are crucial for a successful and long-lasting finish. If unsure, it's advisable to consult with a professional or refer to the manufacturer's guidelines.
3. How do I prepare the boat's surface for painting?
Surface preparation is crucial for a successful paint job. It typically involves cleaning the surface, removing any loose or flaking paint, sanding or scraping to create a smooth and clean surface, and applying primers as necessary. Follow the specific instructions provided by the paint manufacturer.
