Why Intumescent Coating?

Charmor productIn case of fire, the temperature can easily and quickly become high. When the temperature reaches 500-550⁰C the steal beams might collapses due to the heat. Intumescent coating is used on the beams to isolate them from the heat and hence prolong the evacuation time as well as extend the time to extinguish the fire with several hours. Time that can save lives. Already when the temperature reaches around 200⁰C, the intumescent process starts. This means that the coatings forms a thick foam that protects the beams from the fire and the heat.

Our Charmor™ provides you with the critical carbon source essential to achieving top quality intumescent coatings. Charmor™ polyols can be used in both waterborne and solventborne formulations. If you are looking for more sustainable solutions, then Charmor™PM40 Care is the perfect solution.

Perstorp is a leading global supplier of high purity micronized polyols for superior intumescent coating formulations. Under the trusted Charmor™ brand we can provide you with the critical carbon source essential to achieving top quality intumescents. Charmor™ polyols are based on Penta and DiPenta and can be used in both waterborne and solvent formulations. If you are looking for more sustainable solutions, then Charmor™PM40 Care offers the perfect solution.

Designed for the best performance & protection

The polyols are precisely milled to a consistent, small, and narrow particle size, which provide superior fire protection properties, and reliable performance every time.  Charmor’s higher char volume and very good insulation win valuable time by delaying the effects of fire and building collapse to save people and property.

The range is suitable for both indoor and outdoor approved intumescent paint formulations. Aesthetically there are no restrictions using Charmor™ in intumescent coatings, allowing designers and architects the freedom to achieve the desired finish without compromising safety.
