Introduction
Flame Seal FX950 is a water-based Intumescent paint/fireproof paint that can be applied to most substrates including, lumber, plywood, OSB, and Gypsum. FX950 is fully tested and has a rating ranging from Class A to 2 hours to meet building codes domestically, internationally, and for the Wildfire Urban Interface. When Flame Seal FX950 is exposed to fire or extreme heat, a protective layer of Carbon Foam develops and prevents the fire and heat from transferring to the substrate. FX950 is a low VOC fire-resistant paint with a smooth white architectural grade finish. This product can be paired with a primer and a top-coat. For best application Flame Seal recommends using an airless sprayer, please see the application guide for more information.
