Technical Details & Test Data
- Directions for Use
Grounding: Grounding is best executed by means of a non-oxidizing metal plate bolted to the floor. Contact resistance is significantly reduced if a conductive rubber pad is used in addition to the metal plate top. The grounding plate can then be led to the earth via a bonding point and ground cord. ECP 1440/500 grounding kit is available as a standard product for this application.
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 4 parts of base paint to 1 part harder. Typically a 4.0-liter pack of paint can be mixed with a 1.0-liter pack of the hardner. The coating can be applied by brush or roller.
Maintenance: The painted floor should be kept clean to avoid soiling shielding the electrostatic conductive properties of the floor, therefore a regular cleaning regime should be implemented using non-abrasive and non-aggressive techniques. Regular checks of the grounding arrangements should also be carried out.
Preparation: 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.
It is recommended that a sealer is used on floors before coating with ECP 575 and that the following preparations are undertaken:-
New concrete - in the case of newly laid concrete it is important that the concrete has been allowed to dry 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 acidly 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 recognized methods:-
- Abrasive blast cleaning - this 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 solution to be removed safely.
- Resistance Properties
- ECP 575/JSF182/182 exhibits excellent mechanical properties which will withstand abrasion and impact as well as give good resistance to a wide range of chemicals including oils, fats, solvents, acids and alkalis.
- The electrical properties of the paint are permanent and independent of humidity, a conductive underlay is not required for grounding the system. Additionally ECP 575/JSF182/182 provides the option of directly grounding racking/shelving used for storing ESDS's (electrostatic sensitive devices) to the floor.
- For personnel grounding applications the product is best used in conjunction with suitable electrostatic dissipative footwear eg, ECP 1450 series foot straps.
