INSULATING GLASS SEALANT

摘要

A two-part sealant composition, wherein this composition comprises a first part and a second part. The first part comprises a polymer selected from a silane-terminated polyurethane or a silane-terminated polyether, wherein this polymer is present in an amount of up to 100% by weight of the first part of the sealant composition. The second part comprises a plasticiser that it is compatible with the polymer and a filler comprising at least 0.5% by weight of residual water, wherein the filler comprises at least one rheological filler, and wherein the filler is present in an amount of 80-20% by weight of the second part of the sealant composition. The first and second parts are separated from one another, and the amount of polymer present in the first part makes up 4-50% by weight of the first and second parts taken together. In use, the first and second parts are mixed to achieve a cured substance having a 48 hour Shore A hardness in the range of 25-70.
