PRODUCT CHARACTERISTICS SIGMACOVER 256 SIGMA PROTECTIVE AND MARINE COATINGS
- General-purpose epoxy primer or buildcoat in protective coating systems, for steel and concrete structures in atmospheric exposure
- Suitable for atmospheric industrial and marine applications
- Can be recoated with various two-component and conventional coatings, even after long weathering periods
- Lead- and chromate free
- Excellent rust preventing properties in industrial or coastal atmospheres
- Tough, with long-term flexibility
- Cures even at temperatures down to -10°C (14°F)
- Good adhesion to steel, galvanized steel and aged epoxy coatings
- Easy application, both by airless spray and brush
- Can be used as epoxy primer/finish (for dry internal areas)
RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES
- Substrate conditions
- Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)
- Shop primed steel; pretreated to SPSS-Pt3 / SSPC-SP3
- Galvanized steel must be sweep blasted until an even flat appearance (only for internal dry exposure conditions)
- Aged suitable coating must be dry and free from any contamination
- Substrate temperature
- Substrate temperature during application and curing down to -10°C (14°F) is acceptable; provided the substrate is free from ice and dry
- Substrate temperature during application should be at least 3°C (5°F) above dew point
- Relative humidity during application and curing should not exceed 95%
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 (59°F), otherwise extra thinner may be required to obtain application viscosity
- Adding too much thinner results in reduced sag resistance and slower cure
- Thinner should be added after mixing the components
Pot life
- 8 hours at 20°C (68°F)
- Note: See ADDITIONAL DATA – Pot life
Air spray
Recommended thinner
THINNER 91-92
Volume of thinner
10 - 15%, depending on required thickness and application conditions
Nozzle orifice
1.5 – 3.0 mm (approx. 0.060 – 0.110 in)

Frequently Asked Questions
1. Can I use the same paint on the hull and topside areas?
The hull and topside areas have different requirements, so it's recommended to use specific paints designed for each area. Hull paint is typically formulated for underwater use and has antifouling properties, while topside paint is more suitable for above-the-waterline areas.
2. How can I maintain the painted surfaces on my boat?
Regular maintenance is crucial to extend the life of the painted surfaces on your boat. This includes cleaning the surface regularly, avoiding harsh chemicals or abrasive materials, addressing any damage or scratches promptly, and applying touch-ups or recoating as necessary.
3. Can I use marine paint for non-marine applications?
Marine paint is specifically designed for marine environments and may not be suitable for non-marine applications. However, some marine paints can be used for other applications such as outdoor furniture or metal structures, depending on the specific product and manufacturer's recommendations.
