r451 eau
A two component anti-fire polyurethane cycle which consists of the basecoat R451 EAU and the relative protective topcoat R451 EAU TOP available in different RAL/NCS colours. Its fire-retardant properties are based on decomposition reactions that starts when, under the action of heat and temperature, the coating releases substances able to slow the process of carbonization of the wood. In addition to its fire-retardant reaction, the complete coasting system is characterized by hardness, good resistance to stains and scratching, softness of the finish and rapidity of hardening of the various coats ensuring the user of excellent times and results for this type of product.

The fire-retardant product has been classified in EUROCLASS B, s1, do based on data from fire reaction tests carried out in conformity with the European norm EN 13501-part 1 and in CLASS 1 based on the norm UNI 9796/2014 according to D.DM. 6/3/92 (BL158PVI100020). This classification is for the protection of all types of wooden-based supports either walls or ceilings, as specified in EN 13823-Reaction to fire tests for building products exposed to thermal heat of one single burning item and EN ISO 11925 Reaction to fire tests – Ignitability of building products subjected to direct impingement of flame – Part2: Single-flame source test.
The above data is purely indicative and refers to the test of white cycle. The application characteristics of the product has been obtained with an application of 150 microns (200C, relatively humidity 60%). Different thickness and/or temperature and/or humidity might imply data variation.
Information about the utilization and consumption of R451 EAU in every step of the product life cycle is detailed in the relative Material Safety Data Sheet (MSDS).
