AEROSIL® Fumed Silica for Fire-resistant glass

AERODISP® W 1244 dispersion is a ready to use dispersion specifically developed for manufacturing high performance potassium silicate based intumescent interlayers for fire-resistant glass through a “Cast-In-Place” process.  This dispersion contains all the necessary additives for achieving an effective radiant heat barrier in case of fire and also for maintaining the glass transparency in low temperature conditions. The high purity and special morphology of the AEROSIL® particles used, and the controlled particle size distribution achieved through Evonik know-how in dispersion techniques, confer to this product its unique properties. Specifically this dispersion allows:

· A simpler, more controllable, and more reproducible manufacturing process which minimizes the required investments.

· An optimized composition of the interlayer for achieving maximum performance in case of fire.  

· Outstanding optical quality of the final glass.

Additional information on the use of AERODISP® W 1244 for manufacturing fire-resistant glass is available in our Technical Information TI 1407. If you are interested in starting production of fire-resistant glass with AERODISP® W 1244, Evonik can provide a guideline formulation, the description of manufacturing procedures, and a list of the necessary equipment for production start-up.  It has never been so easy. We stand by your side to set up the production and accompany you in the process until you manufacture high quality fire resistant glass.
