Perstorp has extended its CharmorTM range of micronized polyols for intumescent coatings for fire safety treatment of steel building structures, offering light weight and aesthetic quality. Charmor is available for both water-based and solvent-based coatings and with two particle sizes (15 or 40 microns). The new Charmor Care uses raw materials partly derived from renewable sources.
Charmor provides a reliable, high consistency, performance carbon source to combine with other PIN components of intumescent systems to form, in case of fire, an insulating carbon foam or char several centimetres thick.
