Method of Use

Surface Preparation

Surface must be dry, clean and in sound condition. Remove oil, dust, dirt, mill scale or other foreign substance to ensure good adhesion. Minimum surface preparation methods to be followed for:

1. Iron and steel: For immersion service, abrasive blasting to a minimum near white grade (SSPC- SP-10, NACE2) with a 50-75μm surface profile is recommended for optimal performance.

All weld spatter must be removed along wield seams, rough welds should be ground smooth, and all sharp edges should be ground to a smooth radius.

For non-immersion service, abrasive blasting to a minimum commercial grade (SSPC-SP-6, NACE3) with a 50-75 m surface profile is recommended for optimal performance. Abrasive blast cleaned steel requires two coats.

2. Aluminum and Galvanizing: brush blast, 50μm profile

3. Concrete and masonry: should be cured at least 28 days, cleaned, dry, and sound.

Remove curing compounds, form oil, salts, laitance and other contaminants. For best results, sand blast or acid wash with 15% Hydrochloric acid and thoroughly rinse with water. Concrete should be cleaned and dry before coating. For immersion service, abrasive blast referencing (SSPC-SP-13NACE16) surface preparation of concrete.

4. Wood: All coatings should be removed. Wood should be rough sanded.

Mixing

E-COAL 90 is supplied in pre-weighed units consisting of base and hardener. Power mix base component before adding hardener, then thoroughly mix the entire contents of the two components for at least two minutes.

Add the required amount of E-COAL 90 thinner.

Note: Both components will thicken in viscosity when cold. The material should be warmed to room temperature before mixing for best results

Application

E-COAL 90 can be applied by brush, roller, airless or air type sprayers.

Apply only when air and surface temperatures are between 10°c – 35°c and surface is at least 3° c above.

dew point. For immersion service and severe environments, a total dry film thickness of 400μm applied in 2 coats is required, airless spray is preferred.

Storage

Keep the containers in a dry, cool, well-ventilated space and away from source of heat and ignition. Containers must be kept tightly closed.

Shelf life

12 month in original closed packing.

Safety and Handling Precautions

Keep away from heat, spark and open flames.

Avoid contact with skin or eyes. In case of contact, wash skin with soap and water.

Keep container closed and store in cool, ventilated area when not in use. Proper ventilation and protective measures must be provided during mixing, application and drying, to keep vapor concentration within safe limits and to protect against toxic hazard.
