- Intended Uses
A marine grade potable water certified epoxy tank coating for new builds when used as a single coating which can also be used in ballast tanks, void spaces, cofferdams and wet spaces. For use in maintenance and repair when used with Easy Prime.
- Surface Preparations
- Simply stated the steel surface must be:
- Clean : No staining to white rag when rubbed across steel surface
- Dry : No visible moisture on the steel surface
- Tight : No loose material when a wire brush is pulled across the surface of the metal
- For new build sweep blast entire tank to Sa1.0. For maintenance and repair refer to Easy
- Prime surface preparation. A surface profile of 50 - 100 microns is required.
- Weld Seams and sharp edges must be stripe coated with Easy Flex
- Application
Film Thickness
- New Build: 12 Wet Mils (300 microns wet).
- Maintenance: 9 Wet Mils (225 microns wet).
Theoretical Coverage
- 3.29 m²/liter (134 Ft2/Gall) at 12 Mils , add 20% for overspray loss.
- 4.37 m²/liter (178 Ft2/Gall) at 9 Mils , add 20% for overspray loss.
Method of Application : Overspray loss. Airless Spray, Brush, Roller
Mixing
Material is supplied in a Uni-Pak container. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified.
- Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.
Thinner
Not recommended.
Airless Spray
Recommended
- Tip Range 0.53-0.58 mm (21-23 thou)
- Total output fluid pressure at spray tip not less than 211 kg/cm² (3000 p.s.i.)
- Mixed material temperatures should be between 30-35°C (86 - 95°F) for optimum spraying.
Conventional Spray
Application by conventional spray is not recommended
Brush
Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.
Roller
Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.
Cleaner
Methyl Ethyl Ketone (CAS # 78-93-3)
Work Stop / Cleanup
Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with Cleaner. Once units of paint have been mixed they should not be resealed and it is advised that after prolonged stoppages work recommences with freshly mixed material. Clean all equipment immediately after use with cleaner. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays. Do not exceed pot life limitations. All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation.
Welding
In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation.
- Limitations
At ambient temperatures below 25°C paint lines must be lagged. In-line heaters should not be used unless absolutely necessary. For maximum performance the curing temperature should be kept below 35°C. Particular care should be taken to avoid exceeding this in localized areas when artificial heating is introduced. The climatic conditions within the tank must be controlled to maintain a maximum relative humidity of 90%. The drying times and overcoating intervals may alter due to various on-site factors such as tank configuration and ventilation rates.
