  • Patent number: 5221339
    Abstract: The silicone oil compound of the invention has a high thermal conductivity by virtue of compounding of a relatively large amount of a heat-conductivity improver such as zinc oxide, aluminum nitride and the like in a powdery form but still has an adequate and stable consistency suitable for application. This unique characteristic is obtained by the use of a specific silicone fluid as the base of the compound, which is a diorganopolysiloxane of which from 5 to 50% by moles of the silicon atoms at the molecular chain ends each have a hydroxy group bonded thereto.

  • Patent number: 5190818
    Abstract: The adhesive composition of the invention exhibits an adequately controlled adhesive bonding strength when paper sheets coated therewith are bonded together to be adaptable to subsequent separation of the bonded sheets of paper by peeling. The essential ingredients of the adhesive composition include: (a) a rubber latex; (b) a silica gel powder having a specified average particle diameter; and (c) a starch, preferably, having a specified particle diameter, e.g. wheat starch, each in a specified weight proportion. In addition to the good balance between the reliability of the adhesive bonding and subsequent peelability, the paper sheet coated with the adhesive composition is prevented from a decrease in the adhesiveness even when the surface is contaminated with a silicone oil and from the troubles due to blocking when adhesive-coated sheets are stacked one on the other with the adhesive-coated surfaces in direct contact with each other.
