Introduction

Two-component amine-cured highly abrasion-resistant solvent-free phenolic epoxy coating.

Key properties

• Suitable for single-coat systems for underwater coating protection of icebreaker hulls; forms a smooth, tough film that is easy to clean and remove fouling.
• Coating certified by Lloyd's Register for resistance to ice impact and abrasion.
• Excellent abrasion and impact resistance.
• Can be used as a long-term heavy-duty corrosion protection coating system for decks with demanding abrasion resistance and impact resistance requirements, such as vehicle decks on Ro-Ro ships and livestock decks on livestock carriers.
• Low coefficient of friction.
• Compatible with well-designed cathodic protection systems.
• Also suitable for compartments or other steel structures requiring high abrasion resistance.
• High resistance to crude oil; suitable for cargoes up to 120 °C (250 °F).
• Good chemical resistance, suitable for carrying and storing a wide range of chemicals and solvents.
• A heavy-duty single-component high-pressure airless spray pump (pressure ratio 60:1) may be used.
• Curing temperature can be as low as 5°C (41°F).
• With no severe damage to the coating, the expected protective life of the coating exceeds 20 years.

Colour and gloss

• Light grey, dark grey, red-brown, black (other colours available by customization).
• Gloss.

Recommended substrate condition and temperature

Substrate condition

• Bare steel: blast cleaning to Sa2½ of ISO 8501-1, with a surface profile of 50–100 µm (2.0–4.0 mil).
• The substrate surface must be clean, dry and free of all contaminants.

Substrate temperature and application conditions

• During application and curing, the substrate temperature must be above 5 °C (41 °F).
• During application, the substrate surface temperature must be maintained at least 3 °C (5 °F) above the dew point.

Instructions for use

Mixing ratio by volume: base : curing agent = 80 : 20.

• Before application, the temperature of the base and curing agent components, or of the mixed paint, shall be adjusted to at least 20 °C (68 °F).
• At low temperatures, spraying may be difficult because of high paint viscosity.
• No thinner shall be added.

Induction Time

Not required.

Airless spray (single-feed pump)

• Two-component airless spray pump with external heating.
• Heavy-duty single-component high-pressure airless spray pump with a pressure ratio of 60:1 and a high-pressure hose of suitable length.
• For low-temperature application, use heated or insulated hoses to prevent the paint from thickening in the lines.
• Keep hoses as short as possible.

Brush/roller

• For local small-area repair and manual touch-up only.

Notes

• All application equipment must be cleaned immediately after use.
• Paint remaining in spray equipment must be fully discharged within its pot life.

Supplementary parameters

Film thickness and spreading rate

Wet film thickness measurement

• Differences often occur on site between wet film thickness readings and actual film thickness because of the thixotropic properties and surface tension of the paint, and the slow escape of air entrained in the paint,

The air usually remains in the wet film for a period, temporarily occupying a volume fraction of the coating.

• During application, control the wet film thickness to the nominal dry film thickness plus 60 µm (2.4 mils).

Measure dry film thickness

• Because the coating has low initial cure hardness, a film thickness gauge probe sinks into the film and gives inaccurate readings if dry film thickness is measured in the first few days.
• When measuring dry film thickness, place a calibration shim of known thickness on the coating at the test point, then gently press the probe of the film thickness gauge onto the shim to measure

the film thickness.

Safety Precautions

• For the coating and its recommended thinners, see Safety Sheets 1430 and 1431 and the relevant Material Safety Data Sheet.
• Although solvent-free, the coating must be handled with care; avoid inhaling spray mist and contact of uncured paint with skin and eyes.
• In confined spaces, provide adequate ventilation to maintain good visibility.
