Intumescent coatings protect steel from fire by expanding to form a protective char layer. Components: carbon source (pentaerythritol), acid source (ammonium polyphosphate), blowing agent (melamine), binder. Selection criteria: required fire rating (30-150 min), DFT (1-3mm), substrate (primed steel, galvanized), and environmental exposure. SGTECH fire retardant series offers 30-150 min ratings with smooth finish.
