Abstract:
A fire-resistant polyurethane composition and a fire-resistant product comprising the fire-resistant polyurethane composition. The fire-resistant polyurethane coating composition comprises: an aromatic isocyanate component, a polyol component, and an intumescent component; wherein the aromatic structure in the polyurethane backbone is ≥24wt%. The fire-resistant polyurethane composition could provide surprisingly good intumescent layer toughness as well as good insulation performance.
