Description Single pack thin-film Solvent based fire protection coating for exterior use on steel sections in accordance with BS 476; Part 21

Fire Rating FS370 - 30 to 120 minutes Approvals BS476: by Certifire Application Areas • Structural steel members as columns, beams, girders and framework

• 1/H-sections and Hollow Sections • Also on galvanized members • Excluded are steel constructions permanently stressed by ponding water due

to rainfall or condensation or aggressive gases • Fire resistance rates R30 - R120 • For external use

Benefits • Extremely low DFT • Extra fine granulated raw materials guarantee a smooth surface • Maintenance-free • Easy to handle • Top coat in RAL, NCS or individual colour shades available • VOC<350g/l

Instructions for the Application of FS460 & FS470 KS - Indoor

• FS370 Outdoor should be preferably applied at a temperature of ≥ 5oC and at ≤ 80% relative humidity. In case of high relative humidity e.g. 80% good ventilation conditions are essential.

• Substrate temperature should at least be +3oC above dew point and in any case above 0oC

• FS370 Outdoor should only be applied by trained installers Surface Preparation • FS370 Outdoor is designed to be applied over suitably prepared and primed

substrate • The compatibility between FS370 Indoor and unknown already applied primers

would need to be reviewed; any damage (corrosion, impact etc.) must be repaired carefully with an approved primer; a DATA sheet and MSDS is required or ask the Fire Security Systems service team for technical support

• For bare profiles sandblasting Sa 2.5 according to EN ISO 12944-4 or manual cleaning St 2 is recommended

• On galvanized steel an approved primer is recommended • Surface has to be cleaned to remove contamination and to secure adhesion • Incompatible primer must be removed by acceptable techniques and

subsequently primed with an acceptable primer. One technique recommended is commercial blast cleaning as outlined in the Steel Structure Painting Council (SSPC).

• Generally we recommend to record the application data according to EN ISO 12944-7 I -8

Application • Stir thoroughly before application Airless spraying

• A material temperature of about 20oC is recommended for optimal spraying behavior

• If needed thinning with max. 5% solvents: 85% Xylene (Cas-No. 1330-20-7 ) and 15% Solvent Naptha (CAS-Nr. 64742-95-6)

• Recommended operating pressure: 200 - 250 bar • Nozzle sizes: 0.017 " - 0.025 " ; flow rate > 4 L/min • Machine and gun filters and screens should be removed • Up to 1000g/m2 can be applied in one layer • 1st layer on primer: wet film thickness approx. 500 microns - DFT approx. 350

Technical Data Sheet FS370 Outdoor

microns • Typical coverage rate of FS370 Outdoor applied in one layer depends on the

type of steel specimens and the position within the construction Brushing and rolling

• Rolling by lambskin mohair roller, resistant against solvents • Brushing with long-bristled brushes; resistant against solvents

Drying • At 20oC object temperature and 65% relative humidity at least 24 hours between each coat

• Lower temperatures, higher relative humidity, insufficient air movement and different fire protection coating thicknesses can prolong drying time

Top Coat • Application of topcoat after through-drying of FS370 Outdoor, thus after at least 48h

• Thorough-drying of FS370 Outdoor can be checked by fingernail test • Topcoat with an approved coating • Available in RAL or NCS colour shades and on request individual shades

Transport / Storage • Transport and storage free from frost- preferably at a minimum of +5oC to a maximum of +30oC

• Shelf-life of unopened pails: 12 month from date of manufacture • Opened pails must be sealed completely

Packaging • 25 kg net weight (19 Litres or 5 Gallons) • Tinplate buckets • Other sizes on request
