In case of temperatures between 200\u00b0C and 300\u00b0C the fire-retardant additives release substances, inhibiting oxygen: they develop carbon dioxide or create water vapor, effectively decreasing the temperature of the combustion. Between 300\u00b0C and 400\u00b0C the fire-resistant coatings start the crystallization process. Essentially, a non-flammable vitrified layer creates a barrier for the wood.[\/vc_column_text][\/vc_column][\/mk_page_section][mk_page_section bg_image=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/vernici-ignifughe.jpg” bg_image_portrait=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/bk_cicli_mobile.jpg” bg_position=”left center” bg_repeat=”no-repeat” bg_stretch=”true” enable_3d=”true” padding_top=”200″ padding_bottom=”200″ sidebar=”sidebar-1″][vc_column width=”1\/2″][vc_column_text el_class=”white rennertitle” css=”.vc_custom_1554661633463{margin-bottom: 0px !important;}”]Protective barrier
\nand insulation[\/vc_column_text][vc_column_text el_class=”white rennerp” css=”.vc_custom_1554661645333{margin-bottom: 0px !important;}”]The intumescent additives react at a temperature of 200\u00b0C, by inflating the coating film. Thus, they create a protective and insulating barrier, delaying both combustion and raising of the temperature. Normally, the flame-retardant additives are used in systems, which are applied on furniture, while the most reactive intumescent additives, which are not very transparent, are used in coatings, which are used to paint load-bearing structures.
\nTherefore, a fire-resistant coating, certified in Class 1 of Reaction to Fire, will contain flame-retardant additives and will be more performing concerning chemical and abrasion resistance, while an intumescent coating, certified in Class of Resistance to Fire, will be more sensitive to humidity and stress.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][\/vc_column][\/mk_page_section][mk_page_section bg_image=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/smoke-1.jpg” bg_position=”center top” bg_repeat=”no-repeat” bg_stretch=”true” enable_3d=”true” padding_top=”100″ padding_bottom=”200″ sidebar=”sidebar-1″][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][vc_video host=”self_hosted” mp4=”http:\/\/vernicifirewall.it\/wp-content\/uploads\/video\/BASSI_IT.mp4″ poster_image=”http:\/\/vernicifirewall.it\/wp-content\/uploads\/video\/intervista-bassi.jpg” custom_thumbnail=”true” thumbnail_image=”4302″][mk_padding_divider][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/mk_page_section]\n","protected":false},"excerpt":{"rendered":"
