ECP 527
TWO PACK
POLYURETHANE COATING.
ECP 527 is a two-pack polyurethane coating that provides high levels of weathering, colour retention, solvent resistance, abrasion resistance and wide-ranging chemical resistance.
ECP 527 can be applied to ferrous and non-ferrous metals, wood, concrete, asbestos, fibreglass etc.
Typical installations include:
- Electrical industry.
- Petrol/ Chemical industries.
- Water treatment plants.
- Food Industry- Machinery and surfaces.
- And many other industrial uses.
ECP 527 is a slow curing system, being dust free in 4-6 hours, firm dry in 24 hours and fully cured in 5-6 days @ 20 °C°.

Application:
The base paint must be thoroughly mixed to ensure complete dispersion of the conductive medium. Hardener should be thoroughly mixed into the base paint in the ratio 2.25 parts of base paint to 1 part hardener. The coating can be applied by either brush, roller or spray.
For spray work, thinner should be added to give a viscosity of 25-35 seconds on No.4 BS Flow Cup.
Moisture in ECP 527 should be avoided so all equipment must be carefully dried, ensuring brushes, spray guns, and airlines are clean and free from traces of oil and water.
Preparation:
N.B. As with all paints it is suggested that a small trial be performed before the complete area is coated and when dry tested for adhesion, appearance and resistance.
Ferrous metals: Blasting, followed thorough cleaning and degreasing, for light ferrous metals clean, degrease and abrade. If metal work has been painted previously, abrade to expose as much metal work as possible to ensure good grounding.
Non- ferrous metals, clean, degrease and abrade, use etch primer.
NEW CONCRETE:
In the case of newly laid concrete, it is important that the concrete has been allowed to dry out for a minimum of 28 days before considering applying a concrete sealer, moisture content should be below 6%.
The main problem with new floors is the weak surface layer (laitence).
This water rich top layer forms during the drying out period and is mechanically weak.
The laitence has a chemical composition different to the rest of the concrete. The surface should therefore be acid etched to remove the laitence.

OLD CONCRETE:
Remove all oils, grease, dirt etc. together with the removal of old or failed coating to ensure a sound base. In order to ensure good adhesion and long-term performance of the coating, it is essential that the correct type of surface preparation is carried out.
The following are recognised methods: –
ABRASIVE BLAST CLEANING:
Should always be the first choice for heavy duty systems if conditions allow.
SCARIFYING:(or “scrabbling”)
Rotating wheels and brushes scour the concrete surface.
ACID ETCHING:
This method is most suited for use on new concrete floors and is used to remove laitence, it will not remove old paint, oil or grease. It should only be used where sufficient drainage exists to allow the water and acid solutions to be removed safely.
