One of the purposes of fire retardant coatings is to reduce the rate at which the fire spreads and thereby retard it. As regards fire protection, most countries have very strict regulations concerning the performance of fire-resistant and fire -retardant coatings, especially for the treatment of bearing structures, coatings and wooden works. Wood exhibits an important aesthetic importance and fire retardant coatings for wood should combine fire protection with excellent aesthetic results. "Safety performance and Finish performance". Customers' requirements are not only regulation -related (compliance with law), but they are also appearance/functional- related. These are two components that since the design stage have been atthe basis of Sayerlack's progress towards the realisation and formulation of fire retardant coatings. When it is mandatory to conform to fire regulations, the architect/designer or authoriser issuer of the fire certificate may calculate the fire load (quantity of flammable material per square metre and relevant calorific power) for each room, assessing the class that each construction element falls into, based on emergency exits, fire fighting systems, or internal permanent safety services. Protection from fire: where is it required? • Public buildings • Offices/factories • Clubs, bars, pubs and dance halls • Banks • Airports and railway stations • Hotels and tourist facilities • Exhibition centres, meeting and fair venues • Shops • Schools, colleges, universities and nursery schools • Auditoriums, theatres, cinemas and museums • Hospitals • Gyms and fitness centres • Churches • Civil buildings ire reaction - Test UNI 9174 3 4 1 .` Test start on MOF coated with a normal polyurethane cycle. - Test start on MDF coated with the TB cycle. 1 _ f � . t 6 The 750 Co heat of the radiant panel sets the coating film on fire. - Even if only partly damaged, the reaction that reduces the comhustion speed is evident on the panel. I 'U Without protection, the flame reaches the imad. The combustion sets off but the flame propagation speed is greatly reduced by the fire retardant coating. The panel is 50% charred. The situation is almost unchanged, the damaged area is minimal and the flame tends to extinguish. FIRE REACTION M.O. 26/6/84 - M.D. 6/3/92 CUNI 97963 - Ministry of Internal Affairs Italy Fire reaction regulations divide coating and panelling related materials, as well as flooring, false ceiling, furnishing and seating surface materials, into several classes. Italian regulations, one of the strictest in the EU in terms of fire reaction performance, assigns six classes. They are assigned a fire reaction class, which ranges from 0 (non-flammable) to 5 (easily flammable). In the event of a fire in a closed place, temperature reaches very high values. Wooden materials start to release gases that considerably contribute to fire propagation. Class 1 is the best to protect the material involved in the fire. The Sayerlack Class 1 fire retardant systems effectively slow down fire spreading time, as they act with several mechanisms at the same time. For example, an MDF 4 mm thick panel with reaction class 4, after treatment with the Sayerlack fire retardant cycle, obtains the reaction class 1. Our certifications were awarded by the Fire Department - Central Technical Prevention and Safety Direction of Roma Capannelle. Sayerlack's fire retardant products will be tested in the near future also in accordance to new European regulations (Euroclass), this to allow prompt introduction on the market. x`�=�r:L'lorl Lt:slt based on UNI 91174:.

In the event of fire, the temperature reached in a closed room is of several hundreds degrees. Metal, an excellent heat conductor, attemperatures over 4504 C softens and loses all mechanical resistance, and virtually "collapses". Wood, a bad conductor, does not collapse: flames and heat carbonise it's surface, which limits the propagation of combustion to the outer layers. Intumescent coatings increase such protective layer as when heated, they cause a swelling of the coating film (several centimetres) which acts as a barrier to fire. This is why wood is increasingly used in current engineering and architectural works. 0 .ie—, 1 Dry heat resistance test, EN 12722/97 Temperature °C Assessment Remarks 55 not performed 70 5 85 5 100 4 Flawless 120 3 Few isolated Light halo visible from I different directions I Wet heat resistance test, EN 12721/97 FIRA Report: TMCMFC33296 Temperature °C Assessment Rerrcahs 55 5 No damage 70 3 — Disc just visible 85 3 .Disc just visible Surface Resistance to cold liquids, EN 12720/97 FIRA Report: TMCMF03296 Liquid Assessment 7Remarks Ethanol 48% 5 oamage Tea 5 No damage Coffee 5 No damage Cold Oils (24h) 5 No visible damage Cold Fats (24h) 5 No visible damage Resistance to Mechanical Damage BS3962 Part 6:1950 FIRA Report: TMCMFO3296 Test Assessment, Crosscut 5 Cuts smooth Scrape: Surface 5 8.7N penetration Scrape: Penetration 5 20.6N to Substrate ii—ight resistance test, UNI 9427/89 Exposure Grey scale Remarks time (hours) evaluation 20 15 I Flawless WOOD FOR STRUCTURAL USE IN BUILDING The fire behaviour of load bearing wooden structures, which requires passive protection, is totally different from that of metal structures.

Use 20% TH 790 hardener and add 5% of XT 500 additive. Apply 2 coats of 120g/m2. Coating systems, during spray application can lose 20-30% of product due to "overspray". We recommend increasing the purchase quantity of the final product by the same percentage in order to ensure the substrate receives the certified quantity. Losses due to sanding can also occur, sanding should therefore always be very light.
