    摘要: Novel siloxane compounds are provided which have 1-5 hydrogen atoms each attached to a silicon atom (SiH group) and 1-5 epoxy or alkoxy - containing organic groups each attached to a silicon atom in a molecule. These siloxane compounds are useful tackifiers to conventional resins, have good affinity to fluorinated silicone resins and rubbers so that they impart adhesion to fluorinated silicone resins and rubbers, and contribute to solvent resistance and minimal moisture permeability.
