  • MOISTURE CURABLE POLYACRYLATE COMPOSITIONS AND USES THEREOF
    Publication number: 20220315685
    Abstract: Moisture curable polyacrylate polymers with pedant moisture reactive silyl-functional groups bound to the polymer chain and compositions comprising the same polyacrylate polymers are provided. The polyacrylate polymers and the compositions cure by way of a condensation mechanism in the presence of moisture and a catalyst. The moisture curable polyacrylate polymers and compositions provide excellent resistance to automotive oil at high temperature and are particularly useful as sealants and gaskets in automotive powertrains.

  • MOISTURE CURABLE NETWORK SILICONE POLYMER AND USES THEREOF
    Publication number: 20220306864
    Abstract: The present invention provides moisture curable network silicone polymers and compositions thereof, having improved resistance to automotive oil at high temperature. The network silicone polymers contain terminal moisture curable functional groups and a partially crosslinking structure that contains C—C—C linkage which separates the siloxane backbone from the moisture curable functional groups and prevent thermal decomposition of siloxane backbone.

  • Two-Component, Water-Based Lamination Adhesive and Use of the Same to Bond Substrates and Foams
    Publication number: 20220002600
    Abstract: A water comprising, two component polyurethane dispersion adhesive comprising an anionic polyester polyurethane resin and a solvent-free liquid aliphatic polyisocyanate cross-linker. The dispersion can be reactivated one or more times for edge bonding a flexible sheet material onto a substrate having a main surface, a peripheral surface and an edge connecting the main surface and the peripheral surface.

  • MOISTURE CURABLE SILICONE POLYMER AND USES THEREOF
    Publication number: 20200385527
    Abstract: The present invention provides moisture curable silicone polymers and compositions thereof, having improved resistance to automotive oil and high temperature. The silicone polymers contain terminal moisture curable functional groups and a linkage that separate the siloxane backbone from the moisture curable functional groups. The linkage confers oil resistance at elevated temperatures to the cured compositions. The silicone polymers and compositions cure by way of a condensation mechanism in the presence of moisture and a catalyst. The silicone polymers and compositions are particularly useful as sealants and gaskets in automotive powertrains.
