THR600s ≤ 7,5 MJ and EN ISO 11925-2 Exposure = 30 s Fs < 150 mm within 60 s

s1 SMOGRA ≤ 30 m2 / s2 und TSP600s ≤ 50 m²

d0 No flaming doplets/particles in EN 13823 within 600 s

Relative air humidity

Max. 80 %, application temperature shall be at least ≥ 3 K above dew point.

During application and drying of total Pyroplast Wood coating system including Pyroplast Wood Top T, as well as transportation, special protection measures must be taken against weathering.

Substrate temperature Object temperature not below + 10°C, to max. + 40°C
Substrate moisture content At high moisture content of the timber (> 15 %), the coating is unlikely to dry satisfactorily and blooming may result. Therefore the moisture content of the timber should be as near as possible to the level it will stabilize at in use.
Waiting time to overcoating

Overcoatable with topcoat Pyroplast Wood Top T New after approx. 48 hours.

Prior to further applications possible contaminations must be removed.

Drying time

At approx. + 20°C temperature and 60 % relative humidity:

Touch dry after ~0.5 h

Through dry after ~2 h

Different temperatures, different relative humidity and different fire protection coating thickness have an influence on drying time.

Do not stack timber components treated with Pyroplast fire protection coatings.



Ecology, Health & Safety


User must read the most recent corresponding Safety Data Sheets (SDS) before using any products. The SDS provides information and advice on the safe handling, storage and disposal of chemical products and contains physical, ecological, toxicological and other safety-related data.





Application Instructions


Substrate Preparation:

Substrate must be dry, free from dust, oil, wax, grease, dirt, resin, etc.; Existing coatings with poor adhesion have to be completely removed, i.e. with solvent-based paint stripper or to be sanded down.

Surfaces that have been treated with non-acid resistant coatings or release agents such as emulsion paints containing lime, chalk or lithopone should be rubbed down completely. Timber substrates with wetting difficulties should be roughened thoroughly with abrasive paper. The moisture content of the timber should be below 15 %.

Pre-Treatment with wood preservatives:

If resistance to wet rot, fungi or insect attack is requested, we recommend using commercial preservative agents based on oil-alkyd resins provided they are compatible with the Pyroplast fire protection system.

Apply Pyroplast fire protection coating system only after the preservative treatment is completely dry. The moisture content of the timber should be below 15 %. Pyroplast Wood T Primer may be used to allow sufficient adhesion or avoid diffusion of wood ingridients on resinous wood.

Mixing:

Stir thoroughly, free of lumps.

Application:

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. In case of application by roller or brush, additional layers may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to application a trial on site may be useful to ensure that the selected application method will provide the requested results.

Airless Spraying:

  • Material shall be applied undiluted
  • Airless spray equipment with pressure ratio ≥ 30 : 1
  • Filters should be removed
  • Hose diameter not below ⅜ "
  • Whipline ¼ " may be used
  • Recommended nozzle sizes: Pyroplast Wood T: 0.28 - 0.38 mm (0.011 - 0.015 inch)
  • Solvent resistant hoses must be used for Pyroplast Wood Top T

Apply two coats of Pyroplast Wood T to a load of 175 g/m² each coat, in order to obtain a very smooth finish by cutting down wooden fibres, light sanding after the first coat may be recommend (i. e. with 150 grade paper).

Above data shall be used as a guideline with variations being made to suit local conditions.

Brushing and rolling:

  • Material shall be applied undiluted
  • Load natural fine bristle brushes or short pile lambswool rollers are recommended
  • Application of two coats of Pyroplast Wood T to a load of 175 g/m² each coat is recommended

Cleaning of Equipment:

Pyroplast Wood T Primer and Pyroplast Wood T - Immediately after use with warm water.

Pyroplast Wood Top T New - Immediately after use with Unitherm Thinner.
