摘要

The present disclosure includes1) base layer selected from cloth or polymer film2) coated on the substrate layerA silicone adhesive layer containing a volatile organic compound (VOC) releasing additiveReinforcing layers adjacent to the silicone adhesive layerIs a low TVOC releasing silicone composite sheet comprisingWhereThe amount of coating of the silicone adhesive layer isBased on the total coating amount of the silicone adhesive layer and the reinforcing layerLess than 45% by weightPreferably 35% or lessMore preferably less than 20% by weight;Both the silicone adhesive layer and the reinforcing layer areContains or consist essentially of liquid silicone rubber (LSR) or room temperature vulcanized silicone rubber (RTV);AndThe reinforcing layer is(a) organopolysiloxane having an average of one or more silicon atom bonded alkenyl groups in one molecule;Organo hydrophilic polysiloxane;Contains one or more coatings comprising a hydrosilylation reaction catalyst present in an effective amount to cure the composition.The present disclosure further relates to a coating method and a method of reducing TVOC emission.
