Introduction

Two-component high-solids amine-adduct-cured phenolic epoxy primer.

Key properties

• Used as the dedicated matching primer in a two-coat subsea protective coating system, with the phenolic epoxy subsea topcoat 780.
• Maintains excellent compatibility with cathodic protection systems even at high temperatures.
• Meets the pre-qualification requirements of Norsok M-501 (6th edition) System 7 (180 °C / 356 °F).
• Excellent seawater resistance of the coating under immersion.
• Very good anti-corrosion performance.
• Good application properties.

Colour and gloss

• Red-grey.
• Eggshell.

Basic data 20 °C (68 °F)

Parameters after mixing

Maximum 315.0 g/L (approx. 2.6 lb/gal) (theoretical calculated value).

Maximum time: 21 days.

Curing agent: at least 12 months; store in a dry and cool environment.

Notes

• See the supplementary data sheet — theoretical spreading rate versus dry film thickness table.
• See supplementary parameters — recoat interval table.
• See supplementary parameters table — curing time table.

Recommended substrate condition and temperature

Substrate condition

• Blast clean the steel substrate on site to at least Sa 2½ (ISO 8501-1).
• After blast cleaning, the surface roughness should be 50–100 µm (2.0–4.0 mils).
• The steel substrate surface shall be free from rust, mill scale, shop primer and other contaminants.
• During application and curing, ensure the substrate temperature is above 10 °C (50 °F).
• During application and curing, the substrate temperature must be at least 3 °C (5 °F) above the dew point.

Instructions for use

Mixing ratio by volume: base : curing agent = 88 : 12.

• Before application, raise the temperature of the components or the mixed paint to above 15 °C (59 °F); otherwise, thinner may need to be added to adjust the paint viscosity to a suitable application state.
• Excessive addition of water may reduce the sag resistance of the wet film, slow hard drying and even reduce strength.
• The thinner should be added after the two components are mixed.

Notes

• See supplementary parameters — pot life after mixing.

Air spray

Airless spray (single-feed pump)

Brush/roller

• Brush: for local small-area repair and touch-up only.

Cleaning solvent

• Thinner 90-53.

Supplementary parameters

Film thickness and spreading rate

Notes

• Note: maximum dry film thickness for brush application: 80 µm (3.1 mil).

interval

Notes

• The surface must be clean, dry and free of all contaminants.

Curing schedule for a 175 µm (7.0 mil) dry film, with ambient relative humidity of at least 40%.

Notes

• Adequate and continuous ventilation must be maintained during application and curing of the coating.
• After completion, the coating shall be kept at constant temperature to cure for 24 hours with continuous adequate ventilation, after which the ambient temperature may be allowed to fall slowly.

Pot life (at normal application viscosity)

• Refer to this product's material safety data sheet and the product packaging labels for full safety precautions and contingency plans.
• This product is a solvent-borne coating; handle with care. Avoid inhaling spray mist and solvent vapour, and avoid contact of wet paint with skin and eyes.
