NORPHEN 200

Epoxy floor coating

Description

NORPHEN 200 is a bicomponent epoxy-based product used to coat concrete floors. It is made up of:

  • component A:       a mix of fluid epoxy prepolymers and special inert material;
  • component B:       copolymerization amine.

Once completely set, the material has excellent hardness and abrasion resistance qualities, despite being quite flexible. It also offers good general chemical resistance.

NORPHEN 200 forms a pleasing impermeable film with a smooth or non-slip finish, rather shiny, easy to clean, particularly suitable for interiors with special hygiene and easy cleaning requirements.

 

NORPHEN 200 is mould resistant pursuant to UNI EN 15457:2008.

The product is available in coloured and neutral (“colourable”) versions; the latter can be coloured with PREMIX EPOSSIDICO colouring agent.

NORPHEN 200 is CE marked to EN 13813 as SR (“materials for synthetic resin screeds” – prospect ZA.1.5).

Usage field

NORPHEN 200 is used as:

  • a finish coating for STRATOFLEX systems;
  • a surface coating on its own, from 200m to 400m thick, for concrete floors duly treated with acid washing or thorough sanding, with the possible addition of quartz filler or corundum for greater abrasion resistance or greater grip power (anti-slip);
  • coloured floor coating with added look enhancers like FLAKES, glitter particles, etc., finished with clear NORDPUR ESTERNI.

NORPHEN 200

Epoxy floor coating

Substrates preparation
  • the surface must be structurally sound, clean, with no loose material scattered on it, and dry;
  • newly laid floors must have been left to set for at least 28 days and their humidity content (measured with the carbide method) must not exceed 3%; otherwise you must prepare the surface with W3.
  • Because of the impermeability to steam of the film produced, it is advisable to place a steam barrier underneath the concrete, to prevent any humidity coming up from the bottom.
Product preparation

Pour NORPHEN 200 component B into component A and mix well using a drill with suitable attachment (absolutely to be avoided is any manual mixing method); apply with a 40cm steel float or a 25cm short pile solvent roller, according to intended use.

Product application

1)  As a STRATOFLEX finish coating:

  • apply NORPHEN 200 with a roller or steel spatula, after sanding down the surface.

Amount of product required:

  • for a smooth finish with no dusting: 0.2 kg/m2;
  • for a smooth finish with 0.3-0.8 mm light quartz dusting: from 0.7 to 0.9 kg/m2;
  • for a smooth finish with 0.7-1.2 mm light quartz sanding: from 0.9 to 1.1 kg/m2.

 

2)  As a surface coating on its own:

  • Carry out an acid wash with NORDECAL FORTE, brush and rinse;
  • Wait until perfectly dry, then apply a layer of  NORPHEN FONDO;
  • Within max 2 - 3 hours, proceed to apply (with a short pile roller) a layer of NORPHEN 200;
  • The day after, apply a final layer of NORPHEN 200.

Amount of product required:

  • NORDECAL FORTE: 0.1 L/m2;
  • NORPHEN FONDO: 0.25 L/m2;
  • NORPHEN 200: 0.35 kg/m2;

 

3)  As a coloured coating:

  • After preparing the surface as in 2), apply two layers of the product using a roller;
  • When you are applying the second layer, spread  FLAKES on the (wet) surface;
  • The day after, sand down and finish off with NORDPUR ESTERNI TRASPARENTE, in two layers with 6¸12 hours in between.

 

Amount of product required:

  • NORDECAL FORTE: 0.10 L/m2;
  • NORPHEN 200: 0.30 kg/ m2;
  • FLAKES: 50-70 g/m2 (or more, according to choice);
  • NORDPUR ESTERNI TRASPARENTE: 0.25 kg/m2.
Tool cleaning

Use ACETONE or SOLVENTE PER NORPHEN before the product hardens. The hardened product must be removed mechanically.

Warning and informations
  • Adding solvents to NORPHEN 200 can make application easier, but can also reduce chemical resistance and final brightness.
  • Apply any further layer by the following day, max 48 hours later.
  • During the cold period of the year, low temperatures may increase product viscosity, make roller application more difficult, and dull the finish: take the product to a warmer place before applying it and, once applied,  let it set at temperatures higher than +13 °C.
  • The system’s reaction speed is affected by temperature: cold decreases it until it stops completely. During the hot period of the year, keep the product containers in a cool place.
  • Mix NORPHEN 200 components A and B in the exact proportions recommended by the manufacturer; if  necessary, use a balance to weigh out part of the contents.
  • Use NORPHEN SOLVENT to clean your tools.
  • Warning: the hardened product can only be removed by flame or  >200°C hot air.
  • Read carefully the Safety Card.
Preservation

Store indoors at temperatures between +10 and +30°C.
