FLOOR L-TRA

Transparent Two Component Embedding Resin

Description

FLOOR L-TRA is a two component product made up of:

  • Component A: a mixture of liquid epoxy pre-polymers;
  • Component B: copolymerization amine.

Once it has been poured onto the substrate in layers no thicker than 3 mm per coat and after its  subsequent cross-linking, FLOOR L-TRA gives rise to a shining layer of a noticeable transparency and yellowing resistance even on very thick layers.

 

Usage field

FLOOR L-TRA is used as:

  • a specific visible layer behind a transparent surface, where manufactured products of different kind and nature are realized and embedded in the resin;
  • a  transparent protective layer for floor or furniture coatings.

Transparent Two Component Embedding Resin

Application

Preparation of the laying substrate

The area shall be made ready according to state of the art requirements concerning resin floorings: the substrate must be carefully examined to be sure it is structurally sound and a suitable base.

  • Sand and cement screeds must be cured for a suitable length of time (at least 28 days), and have a residual humidity level lower than 3% (carbide measurement); moreover, they must have a minimum compression resistance of 170÷180 kg/cm²; if not, it must be increased deeply impregnating with NORPHEN SW SOLID (diluted as indicated in the data sheet) and taking into account a minimum consumption ranging from 50 to 100 grams of pure product for each cm of thickness to be consolidated.
  • Ready-to-use SC1 screeds can be coated after 8 days (at 20°C and 50% RH).
  • SC 1-R fast ready-to-use screeds can be coated after 48 hours (at 20°C and 50% RH).
  • Screeds realized with a sealant SC 1-BASE like and sands of various origins can be coated after 12÷15 days (at 20°C and 50% RH), after determining substrate moisture content.
  • Industrial quartz concrete can be coated after polishing with diamond wheel or acid wash, with a max. moisture content of up to 3%.
  • Tiled areas shall be roughened with a diamond cup wheel and coated applying a specific multilayer cycle in order to achieve a seamless floor without visible tile joints.
  • Large panels areas of wood can be coated after treating couplings joints with NORPHEN PU reinforced with a GLASS MESH of 160 g/m² (about 5-7 cm wide) and lightly broadcasted to excess with quartz sand 0,1 - 0.6 mm.

 

Substrate specific preparation

Before FLOOR L-TRA is cast, the surface shall be made ready placing on its top objects of different thickness or painting treatments, pictures, screen prints, etc.., consequently:

  • the substrate shall be prepared with a coat of NORPHEN FONDO SL, spread with a spatula for a minimum coverage of 0.45 kg/m², to eliminate the differential absorption and consolidate the substrate;
  • then a coat of NORPHEN 200 or NORPHEN 200 HCR shall be applied, or even NORPHEN LEVEL to create a coloured background on which to operate;
  • in special cases, the substrate can be prepared with W3 COLORATO.

 

Temperatures and mixture useful life

FLOOR L-TRA has a good general reactivity when the laying substrate temperatures ranges from +18°C to +35°C.

Below +18°C, cross-linking speed decreases while the risk of carbonation phenomena, that could alter the area appearance of the hardened product, increases.

Above +35°C, the product is very fluid, but its useful life becomes much shorter and there is the risk that the cross-linking reaction being exothermic could cause yellowing and loss of transparency of the mass of resin.

 

At 23°C, pot life (useful shelf life of the dough) of a mass of 300 grams of product is equal to 30 ÷ 35 minutes: attention shall be paid to the fact that for larger masses, the product accelerates its hardening reaction, reducing its pot life.

 

Product preparation

Poor FLOOR L-TRA Component A into a container, then add component B and mix thoroughly with a professional mixer.

Choose the diameter of the impeller according to the size of the container to ensure an effective mixing of the entire mass and a set number of revolutions capable of keeping the mixer blade always submerged in the liquid in order to limit the embedement of air bubbles inside the mixture.

Mix for about 60 seconds, then stop mixing and, with an appropriate and clean tool (for example a trowel), smooth the inner walls (without abrading them) of the container to facilitate stirring.

Mix approximately for 60 further seconds: once fully mixed, the product A + B must homogeneously wet the wall of the container, forming a film of uniform thickness and free of any discontinuity (“Fish Eyes”).

 

How to use the mixture

Pour not less than 2,8 kg/m2 of product into the area to be coated facilitating (if necessary) the spreading with an adjustable scraper and taking care not to scratch or damage the substrate decoration and the objects to be embedded.

The use of a notched trowel is not recommended if the desired surface should be streaks free.

The maximum thickness obtainable with a single casting is 3 mm, corresponding to a consumption of 3.2-3.3 kg/sqm. To obtain greater thicknesses than 3 mm, subsequent castings should be carried out leaving 24 hours between coats.

In order to ensure a successful functional and aesthetic installation, we recommend:

  • to meet the requirements concerning the substrate range of temperatures to be respected when applying the resin (from +18°C to +35°C);
  • it is recommended to abide by the mixing instructions;
  • to proceed with the laying only when the area temperature is at least 8°C above the dew point (see table at the end of the board);
  • to avoid the use of combustion heating devices with direct discharge into the work atmosphere (preferring the use of electrical appliances) before, during and after the laying of the material;
  • to provide for the use of dehumidifiers whenever air humidity level is high;
  • to avoid contact with water before cross-linking is fully completed (7 days at 20°C).
  • to limit the exposure to direct solar irradiance before curing time is elapsed (at least 7 days) in order to obtain the maximum product performance in terms of transparency and resistance to yellowing.
Tool cleaning

ACETONE or nitro diluent should be used before hardening. After the product has hardened, it should be removed by mechanical means.

Warning and informations

If superficial defects occur due to failure to comply with conditions of use of the mixture:

  • vacuum the area;
  • prepare a monobrush with a white "3M Scotch-Brite" disk;
  • position on the ground a clean cloth, moisten it with acetone and overlap it with a monobrush equipped with disk ;
  • rub the area until the monobrush shedding is wetted with acetone;
  • when the cloth is no longer sufficiently wetted with acetone or when it is clogged by the superficial waste of the coating, before proceeding washing and wringing out the cloth in acetone must be carried out, using rubber resistant to solvents gloves);
  • "Polish" the area gently with a monobrush and a white "3M Scotch-Brite" disc without carving or scratching it, in order to create the micro-roughness needed to make the wax adhere;
  • vacuum the area to remove all traces of residual dirt / dust;
  • apply two "at zero thickness"  coats of NORDPOWDER CERA LUCIDA (coverage: 25-30 g/m2 per coat) with a special wax applicator.

When using the product on decorative metal foils (gold-like foil, silver-like foil, etc...) or on decorative metal pigment-based enamel, a preliminary compatibility test between materials must be done as oxidation / corrosion phenomena may arise and could affect the aesthetic outcome of the application.

When using the product on a low thermal conductivity substrate such as wood, plastics, foams, etc.. both substrate and workplace should be conditioned at a temperature of 25-26°C;

The maximum elapsing time between a product casting and a subsequent one shall be 5 minutes, in fact after that the casting cold shut can become visible and mark the coating once it has hardened.

Components A and B shall be mixed in precise ratios as written on the label: in case of need, ingredients shall be weighed in order to use only part of the package after reading on the package the exact "Mixing Ratio".

Do not apply to:

  • parquet flooring;
  • linoleum;
  • rubber:
  • areas with large problems at coupling joints.

Read the Material Safety Data Sheet.

Preservation
