摘要:
The present disclosure generally relates to adhesive compositions and articles including at least one of polydiorganosiloxane polyoxamide copolymer, silicone polyurea block copolymer, and/or an addition cure silicone, a silicate tackifying resin, and inorganic particle filler. The filler is typically fumed silica. Some embodiments of the adhesive composition include at least one of a polydiorganosiloxane polyoxamide copolymer, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in between about 0.1 wt % and about 20 wt %; a silicone polyurea block copolymer, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in an amount between about 0.1 wt % and about 20 wt %; and an addition cure silicone, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in an amount between about 0.1 wt % and about 20 wt %.
