The present invention relates to a low TVOC emission silicone composite sheet comprising: 1) a substrate layer selected from woven or polymeric films; 2) a silicone adhesive layer coated on the substrate layer and containing a volatile organic compound (VOC) releasing additive, and 3) a reinforcing layer adjacent to the silicone adhesive layer; wherein the coating amount of the silicone adhesive layer is less than 45 wt%, preferably less than 35 wt%, more preferably less than 20 wt%, relative to the total coating amount of the silicone adhesive layer and the reinforcing layer, both the silicone adhesive layer and the reinforcing layer contain or consist essentially of liquid silicone rubber (LSR) or room temperature vulcanized silicone rubber (RTV), The reinforcing layer contains one or more coatings comprising: A). an organopolysiloxane having an average of one or more silicon atom-bonded alkenyl groups in one molecule; B). organohydrogenpolysiloxane; and C). A hydrosilylation reaction catalyst present in any amount effective to cure the composition. The present invention also relates to a coating method and a method for reducing TVOC emissions. |
