PRODUCT CHARACTERISTICS OF SIGMACOVER 435 SIGMA PROTECTIVE AND MARINE COATING
The product characteristics that makes this coating unique are below
- General-purpose epoxy build coat or finish in protective coating systems, for steel and concrete structures exposed to atmospheric land or marine conditions
- Easy application, both by airless spray and brush
- Cures even at temperatures down to -10°C (14°F)
- A high relative humidity (maximum 95%) during application and curing does not influence the quality of the coating
- Good adhesion on most aged, sound alkyd, chlorinated rubber and epoxy coatings
- Can be recoated with various two-component and conventional coatings, even after long weathering periods
- Resistant to water and splash of mild chemicals
- Excellent durability
- Tough, with long-term flexibility
- Resistant to temperatures up to 200°C (390°F) (see SYSTEM SHEET 4062)
RECOMMENDED SUBSTRATE CONDITIONS AND APPLICATION TEMPERATURES
Substrate conditions
- Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)
- Steel with approved zinc silicate shop primer; pretreated according to SPSS or power tool cleaned to SSPC SP3 (SPSS-Pt3)
- Previous coat must be sound, 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 and curing should be at least 3°C (5°F) above dew point
SYSTEM SPECIFICATION
- SYSTEMS FOR BOOTTOP AND TOPSIDE – SYSTEM SHEET 3102
- SYSTEMS FOR DECKS – SYSTEM SHEET 3103
INSTRUCTIONS FOR USE
Mixing ratio by volume: base to hardener 82:18
- The temperature of the mixed base and hardener should be above 10°C (50°F), otherwise extra thinner may be required to obtain application viscosity
- Thinner should be added after mixing the components
- Adding too much thinner results in reduced sag resistance
- Induction time; None
- Pot life; 5 hours at 20°C (68°F)
