Charmor~(TM) micronized polyols from Perstorp respond to increasing calls for high quality intumescent coatings for steel structures

摘要

Coatings containing Perstorp's Charmor~(TM) can help save lives in major fires by prolonging the integrity of steel structures. As building fire safety standards around the world become increasingly strict, Charmor~(TM) puts Perstorp in a strong position to help coating companies satisfy safety-conscious specifiers. Charmor~(TM) polyols are incorporated into coating systems that are applied at a thickness of several millimetres, which under normal circumstances look no different from any other type of coating. However, in a burning building, as the temperature rises to around 200°C and beyond, Charmor~(TM) reacts with other ingredients in the paint formulation to form an insulating carbon foam, or char, that expands to become several centimeters thick. This insulates the steel from the heat of the flames, and so prevents or significantly delays it from collapsing. As a result, building occupants have more time to evacuate the building.
