C-THERM W900
REF. 7I900Description
C-THERM W900 is an intumescent acrylic coating for passive cellulosic fire protection of metal structures. Suitable for interior and exterior use, provided it is combined with the appropriate finish. Formulated to expand when exposed to high temperatures, C-THERM W900 produces a foam with very low thermal conductivity that gives it excellent insulating properties for up to 90 minutes.Main Features
- Fire resistance up to R90
- Thickness per coat: up to 850 µm
- Fast drying
Steel: blast clean the steel to Sa 2½ grade, according to ISO 8501-1. The roughness profile should be adjusted, depending on the thickness of the product to be applied. Remove powder residues and abrasive residues from surface. These indications are generic, applicable to several products and merely informative.
Aluminium: remove oil, grease or soap film with neutral detergent or emulsion cleaner. Blast lightly with fine abrasive.
Galvanized Surfaces: remove any oil soap film using a neutral detergent. Treat the surface in accordance with a lightly blast with fine abrasive. If galvanizing has been exposed to exterior weathering for 6 months or more, remove zinc corrosion products by mechanical means, like power sander. Remove oil grease with the cleaner.
