Intumescent Putty

Product Description

Fitherm® IP is a firestopping sealant based on a polymer dispersion in water and expandable graphite. In case of fire, Fitherm® Intumescent Putty expands up to 25-fold its original volume, and forms a heat-isolating shield. Particularly Fitherm® starts expanding at a relatively low temperature of around 150°C and forms a pressure-resistant char. The outstanding intumescent properties make this product suitable for the most challinging tasks for an intumescant sealant. Fitherm® IP is a halogeen-free and solvent-free product.
