An intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection and require listing, approval and compliance in their installed configurations in order to comply with the national building codes and laws.
The details for individual building parts are specified in technical standards which are compiled and published by national or international standardization bodies like the British Standards Institute (BSI), the German Institute for Standardization (DIN), the American Society for Testing and Materials (ASTM) or the International Standardization Organization (ISO).
At International Coatings Group all our ratings and testing is done with Underwriters Laboratories, who have the highest industry standards.
We currently have two intumescent products FBL-100 and FBL-200.
FBL-100 is a general sub-straight product.
FBL-200 is specifically designed for structural steel, with a slow carbon char expansion.
