PMW (EXT)

Wood

Pigmented fire protection coating system for wood
For outdoor use

Renitherm® PMW (EXT) is an intumescent coating on synthetic resin dispersion base

which forms a carbon char under the effect of heat, thus insulating the substrate.

 

Renitherm® PMW (EXT) fire protection coating for wood insulates against heat,

check the fire, prevents propagation of fire, and diminishes flue-gas density

and flue-gas temperature protects real values for and reduces the risk of damage.

 

Renitherm® PMW (EXT) fire protection coating for wood is classified C-s2, d0 according to EN 13501-1 (SBI-Test) if applied on all sides of the wooden material.

Pretreatment 
​
if resistant to wet rot, fungi or insect with wood attack, we recommend using preservative: commercial preservative agents based on oil-alkyd resins provided they are compatible with the Renitherm® PMW (EXT) fire protection system– apply Renitherm® PMW (EXT) fire protection coating system only after the preservative treatment is completely dry.
