always at the forefront of exciting new technological advances. One such product recently developed by
I
the highly experienced research and development team is the new IRUFIRE B- s1,d0 fire retardant coating system based on two component Pu acrylic-aliphatic coatings. This system has been developed to coat
wooden surfaces which need to comply with the UNE-EN 13823: 2012 Standard of reaction to fire SBI (Single Burning Item) test and be classified according to UNE-EN 13501-2007 + A1:2010 (Euroclasses). The system comprises of a combination
of two main products, IRUFIRE PRIMER IP-1 and IRUFIRE TOPCOAT IT-1 which can be used to create coating systems that either maintain or upgrade to Euroclass B-s1,d0 classification.
rurena through dedicated research to develop the best wood coating, whatever the customer requirement, is
For use as a maintain system, for coating
walls and ceilings of wooden substrates that are flame retardant and are already certified as B-s1,d0 then only one coat of IRUFIRE PRIMER IP-1 at 80-100g/m² is required followed by one coat of IRUFIRE TOPCOAT IT-1 at the same film weight. The only variance for the upgrading coating system is the application of 2-3 coats of IRUFIRE PRIMER IP-1 is required to achieve a film weight of between 400-480g/m². In either system following application and
drying of the clear IRUFIRE PRIMER IP-1 it is lightly sanded with 240-320g abrasive and the sanding dust is removed prior to application of the chosen version of IRUFIRE TOPCOAT IT-1. The upgrade system has been tested on the
standard substrate as defined by EN13238: Reaction to fire tests for building products, conditioning procedures and general rules for selection of substrates. As such the B-s1,d0
classification obtained by this process can be extrapolated to any substrate of wood or wood derivative with a density equal or higher than 510kg/m³. The IRUFIRE B-s1,d0 system has been
certified for application in both clear coatings of any gloss level and pigmented coatings in any gloss level and any colour giving the user ultimate flexibility to ensure that the client requirements are able to be fulfilled. To further assist customers Movac has developed an easy to use calculator which works out the quantity of coating that is required of both the primer and topcoat based upon the area of square metres that require coating.
