METHOD OF USE

Surface Preparation

All contaminants including mould release, grease and dirt must be removed. Mask areas that do not require coating. A suitable primer may be necessary on certain substrates such as Polyethylene and Polypropylene etc.

Mixing and Application

Care must be taken to ensure the concentrate is thoroughly mixed to ensure all the solids are in suspension.

Spray Coating

ECP 502/JSF023 may settle out and regular agitation is recommended during spray application. The paint should be diluted with thinner ECP 502/JSF024 to suit local spray conditions. Typically 2 parts of concentrate to 1 part thinners can be used in a conventional gravity feed spray gun or, alternatively, a pressure pot with agitator. A gun Pessure of 30 psi is recommended. Two passes are normally required to give the optimum thickness and surface resistivity values.

Brush Coating

Brush coat from the can, or thinned to suit the application.

PRECAUTIONS

Highly Flammable - Keep away from sources of ignition - No Smoking (S16). Keep away from heat, sparks and open flames. Keep all containers closed when not in use.

Use Under Well Ventilated Conditions - Do not breath vapour (S23). Harmful by inhalation (R20). In case of insufficient ventilation - wear suitable respiratory equipment (S38), such devices must be used in accordance with the manufacturer’s instructions. For excessive vapour inhalation, remove to fresh air and summon medical attention.

Avoid Contact With Skin And Eyes (S24/25) - In case of skin contact, wash with soap and water, dry and apply work cream. Eye contact - flush with water for at least 15 minutes and seek medical attention. If accidentally swallowed, summon medical attention.
