NORPHEN 200 FUEL

Epoxy Floor Coating

Description

NORPHEN 200 FUEL is a bicomponent product used as surface coating.  It is made up of:

  • component A:   a mix of liquid epoxy prepolymers, pigments, additives and special inert material;
  • component B:   copolymerization amine.

Once set, the material offers excellent general chemical resistance and good reactivity at low temperatures (down to +5°C).

The product is available in a number of colours.

Usage field

NORPHEN 200 FUEL is used as a 200m to 500m coating of aromatic hydrocarbons tanks.

Packaging

NORPHEN 200 FUEL is available in 12 kg packs.

Substrates preparation
  • Carefully examine the surface and make sure it provides a suitable and structurally sound base;
  • according to surface conditions, choose the most suitable treatment to be carried out:

- washing with pressure hot water;
- acid washing;
- sanding;
- diamond wheel sanding;
- scarification;
- sand blasting.

  • That will allow to remove dust, dirt, grease, oil, old adhesives and paint, efflorescence, rust, mould and other foreign material.
  • Any surface depression or irregularity deeper than 3 mm must be evened out with MALTA RAPIDA or alternatively, if smaller than that, with NORPHEN FONDO SL, duly additioned with assorted quartz sands. 
Specific preparation

As a protective coating on dry surfaces in contact with  fuel:

  • Apply a layer of NORPHEN FONDO primer;
  • after 2 - 4 hours, proceed to apply two layers of NORPHEN 200 FUEL with a short pile roller at 24 hours interval.

Minimum amount of product required: 0.35 kg/m2.


In the absence of a steam barrier underneath:

  • apply a smoothing layer of W3 (following technical card instructions), reinforced with glass mesh, to replace any previously mentioned smoothing treatment;
  • after 7 days, proceed to apply two layers of NORPHEN 200 FUEL with a short pile roller, at 24 hours interval.

Minimum amount of product required: 0.35 kg/m2.

As a finish for multilayered floors:

  • On a sanded and vacuumed quartz sand surface, apply NORPHEN 200 FUEL using a steel float.

Minimum amount of product required: 0.7 - 0.9kg/m2.

Product preparation
  • Pour NORPHEN 200 FUEL component B into component A and mix carefully, using a drill with proper attachment; apply as soon as possible, keeping in mind that pot-life is quite short (15 ± 5 minutes at 20C°).
  • In a hot summer weather try not to prepare more than 4 - 6 kg product at a time.

Warning and informations
  • Adding solvents to NORPHEN 200 FUEL can reduce chemical resistance and final brightness.
  • Apply any further layer by the following day, max 48 hours later.
  • Mix NORPHEN 200 FUEL components A and B in the exact proportions recommended by the manufacturer;
  • The system’s reaction speed is affected by temperature: cold weather decreases it until it stops completely, whilst hot weather increases it and makes product handling more difficult.
  • It is good practice to keep the products containers cool in summer and warm in winter, before applying the product.
  • Read the Safety Card.

 

Preservation

Store indoors at temperatures between +8°C and 30°C
