20090022895 | CROSSLINKABLE LIQUID SILICONE COMPOSITION COMPRISING A NOT VERY VISCOSIFYING FILLER BASED ON ZIRCONIUM, USE OF SAME AS FIRE-RESISTANT TEXTILE COATING - The invention concerns crosslinkable liquid silicone compositions whereof the inorganic filler can be increased while observing limits of viscosity compatible with coating of woven or nonwoven supports on an industrial scale, and which impart to the supports thermal properties (reducing calorific power and fire-proofing), impermeability and good mechanical characteristics. To achieve this, a mineral compound is used based on zirconium (zirconia or zirconium silicate) as filler slightly thickening ChZr in a crosslinkable liquid silicone composition. The ChZr has a D; ranging between 3 and 15 m and is used in a proportion of 100 to 350 parts by weight for 100 parts by weight of the silicone composition without fillers. Said silicone compositions may be of the type crosslinkable by polyaddition or polycondensation. The invention is useful for silicone coating textile tarpaulins for indoor or outdoor structures. | 01-22-2009 |
