PPG SigmaShield 1200 is a two-component, abrasion-resistant, solvent-free, amine-cured phenolic epoxy coating. This single coat system is designed for under water hull of ice going and ice breaking vessels and is recognised by Lloyd`s register as an abrasion resistant ice coating.
- Excellent resistance to crude oil up to 120°C (250°F)
- Excellent water resistance
- Reduced explosion risk and fire hazard
- Used at Caspian Offshore Construction, Kazakhstan, on 4 ice breaker vessels, protecting hulls from ice impact
Description
PPG SigmaShield 1200 is a two-component, abrasion-resistant, solvent-free, amine-cured phenolic epoxy coating. This single coat system is designed for under water hull of ice going and ice breaking vessels and is recognised by Lloyd's register as an abrasion resistant ice coating.
Suitable for new construction and for maintenance/repair, PPG SigmaShield 1200 offers excellent abrasion and impact resistance, resistant to well designed cathodic protection and low coefficient of friction.
Top Features & Benefits
- Also suitable for tanks and other structures requiring abrasion resistance
- Excellent resistance to crude oil up to 120°C (250°F)
- Excellent water resistance
- Good chemical resistance against a wide range of chemicals and solvents
- Can be applied by heavy-duty, single-feed, airless spray equipment (60:1)
- Reduced explosion risk and fire hazard
- Gloss finish
- Used at Caspian Offshore Construction, Kazakhstan, on 4 ice breaker vessels, protecting hulls from ice impact, and Bore, industrial shipping services consisting of vessels that have year-round service and Ice Class 1A or 1A Super, suitable for sailing in first-year thin- and medium ice.
- Also used by Baggermaatschappij Boskalis B.V. (Boskalis), a leading global maritime services company operating in the dredging, offshore energy and inland infrastructure sectors, to protect the steel in the hopper of a dredger due to wear and tear caused by sand and stones
Preparation & Application
Recommended Substrate Conditions and Temperatures
Substrate Conditions
- Steel; blast cleaned to a minimum of ISO-Sa2½, blasting profile 50 – 100 µm (2.0 – 4.0 mils)
- Surface must be dry and free from any contamination
- Substrate temperature during application should be above 10°C (50°F)
- Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
System Specification
- The DFT of one layer should not exceed 1100 µm (44.0 mils) on overlap areas in order to avoid sagging
- For abrasion resistant ice coating for ships, 400-500 µm (16.0-20.0 mils) dft is recommended
Instructions for Use
Mixing ratio by volume: base to hardener 80:20 (4:1). When mixing, the temperature of the base and hardener should be at least 20°C (68°F). No thinner should be added. At lower temperature, the viscosity will be too high for spray application.
Induction Time
None
Pot Life
1 hour at 20°C (68°F) / 45 minutes at 30°C (86°F)
Airless Spray
Heavy-duty, single-feed airless spray equipment preferably 60:1 pump ratio and suitable high-pressure hoses. Can be applied with plural component equipment. Contact Rawlins Paints for further details.
Recommended thinner: No thinner should be added
Nozzle orifice: Approx. 0.53 mm (0.021 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.)
Brush/Roller
For stripe coating and spot repair only.
Recommended thinner: No thinner should be added
Cleaning Solvent
PPG Thinner 90-53 or PPG Thinner 90-83
Notes:
Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434). All application equipment must be cleaned immediately after use. Paint inside the spraying equipment must be removed before the pot life has been expired. Due to exothermic reaction, temperature during and after mixing may increase.
Safety Precautions
- For paint and recommended thinners see INFORMATION SHEETS 1430, 1431 and relevant Material Safety Data Sheets
- Although this is a solvent-free paint, care should be taken to avoid inhalation of spray mist, as well as contact between the wet paint and exposed skin or eyes
- Ventilation should be provided in confined spaces to maintain good visibility
