FIRE RETARDANT WOOD COATINGS
- Fire retardant wood coatings (for non-architectural or structural uses)
The term “fire-retardant wood paints” includes a wide range of coatings products mandatory in some places (generally public buildings such as schools, hospitals, gyms, cinemas, libraries, theatres, airports, banks, tourist facilities, fitness centers, exhibition stands, shops, etc.) where it is crucial that the furnishings perform self-extinguishing or fire retarding behaviors so that, once the firing trigger has been stopped, the combustion ends.
The goal is to delay as long as possible the fire propagation since every minute of delay in the flame propagation can be essential to save human lives.
BLAZE STOP
The new generation of fireproof coatings in class 1 (Italian Standards, DM 06/03/1992, most often not valid outside Italy.
According to the UNI 9796/CNVVF/CCI standard, a fire-retardant coating product can modify the fire reaction class of the wood materials on which it is applied.
The standard applies to fire-retardant coating products intended for application on wood materials, with the exception of:
-materials veneered with sliced or peeled wood using adhesives based on thermoplastic resins
– assembled with a cellular structure (for example the honeycomb) or blockboard including air cavities or filled with materials of a heterogeneous nature (for example the rattan: in fact, due to its tubular structure with air cavities, it can not be made fireproof by any type approved fireproof)
According to the Italian Regulations (D.M. 6 March 1992), flame retardant paint products which can be used in activities subject to the fire prevention regulations must be approved. The homologation is issued only by the Ministry of the Interior following the test certificate in which the fire reaction class is indicated.
APPLICATION FIELDS
Our BLAZE-STOP fireproof two-component polyurethanes can be adapted to most of the interior design applications such as claddings, furniture, doors, beading and more, with characteristics and methods of use that are absolutely comparable to the best traditional painting cycles.
EURO BLAZE STOP
The new generation of flame retardant paints for wood in Euro class for manufactured goods destined in the country of the European Union
EU STANDARDS AND REQUIREMENTS
For wood materials and elements, except floors, the European standard governing the reaction to fire classification is the UNI EN 13501-1, while the reaction to fire class is assigned by the following standards:
EN 13823: 2014: fire reaction for construction materials (excluding flooring) exposed to the thermal attack produced by a single burning object.
EN 11925-2: 2005: reaction to fire for construction materials – flammability of products exposed to a direct flame attack. According to the test using only one flame.
Conforming to the Euro classes, the materials are therefore classified: A1, A2, B, C, D, E, F.
Classification A1 is not fuel and those classified as A2, B, C, D, E, and F burn in sequential order.
The European classification also includes the measurement of fumes, dripping and other parameters, which are included in the definition of the reaction to fire class with the following abbreviations:
S: smoke – classified from 1 to 3
D:drops – classified from 0 to 1
By the restrictive EU requirements on reaction to fire and to meet the ever-increasing market demand for such products, our goal was to create a new range of high-performance fire retardant products with uncompromising performance such as:
• improved fire protection performance
• exceptional aesthetic quality of the film
• exceptional physical-chemical features (extremely hard and scratch-proof film with good resistance to degradation, as well as excellent fastness to light)
• better value for money thanks to the minimum quantity required per square meter available on the market for fireproof wood paints.
With these premises, ASTRA VERNICI laboratories have successfully developed and tested an innovative range of 2K POLYURETHANE coatings called EBS (Euro Blaze Stop), to conform with the European standard EN 13501-1 associated with passive fire protection (1).
Note 1)
Active protection:
Active fire protection aims at reducing the effects of fires through their early detection and rapid extinguishing through human intervention or activation of a system (sprinkler systems, alarm devices, fire extinguishers, etc.)
Passive protection against fire:
Passive fire protection limits the effects of fire and allows the evacuation and safety of people and things within a certain period.
