  • Silylated polyurethane/polyorganosiloxane blend and sealant composition and fumed silica composition containing same
    Patent number: 9200160
    Abstract: There is provided herein a composition comprising: (A) a silanol and/orhydrocarbon-terminated polyorganosiloxane in an amount of from about 30 weight percent to about 90 weight percent; and, (B) a moisture curable silylated polyurethane resin in an amount of from about 10 weight percent to about 70 weight percent. There is also provided herein in another embodiment a two part sealant composition wherein the first part comprises: (A) a silanol and/or hydrocarbon-terminated polyorganosiloxane in an amount of from about 15 weight percent to about 60 weight percent, (B) a moisture curable silylated polyurethane resin in an amount of from about 2 weight percent to about 32 weight percent, and (C) a filler, said weight percents being based on the weight of the first part.
    Type: Grant

  • Copolycarbonates, their derivatives and the use thereof in silicone hardcoat compositions
    Patent number: 8637157
    Abstract: Disclosed herein are novel copolycarbonates containing repeating units A and B respectively of the formulae: (A) —[R1OC(?O)O]—, and (B) —[(R2O)n-C(?O)—O]—, wherein the molar ratio of units (A) to units (B) is in the range of from about 9:1 to about 1:9, and wherein R1 is a divalent C8 to C12 alicyclic group, and R2 is ethylene or propylene, and n is an integer ranging from 4 to 40. Also disclosed are silicone hardcoat compositions containing the copolycarbonates and their derivatives. Upon cure, these silicone hardcoat compositions exhibit improved flexibility as compared to that of the conventional hardcoats while at the same time maintain the abrasion resistance of conventional silicone hardcoats.
