  • Patent number: 5300171
    Abstract: A pressure sensitive adhesive tape comprising a tape substrate having at least a portion of one or more sides coated with a silicone pressure sensitive adhesive is constructed using an adhesive which cures to a permanent adhesive. The adhesive is covered on the outer side with a release film, preferably coated with a fluorosilicone release layer, to allow storage of the tape. Preferably the curable silicone pressure sensitive adhesive is cured upon exposure to moisture, the tape therefore being stored in the absence of moisture. A silicone elastomeric structural glazing tape is made by using a silicone elastomer as the tape substrate. The tape can be used to bond glazing panels to building components without the use of other means of fastening.

  • Patent number: 5281455
    Abstract: Moisture-curable silicone pressure sensitive adhesives can be covered with an addition-cured fluorosilicone release coating to provide a releasable laminate. The release force of the laminate is low to moderate and the subsequent adhesion and tack of the adhesive is high and all three values are stable with time.

  • Patent number: 4763600
    Abstract: An apparatus for permanently setting pre-formed creases of a pair of pants comprises a stanchion member and a pair of spaced-apart substantially parallel support members extending substantially horizontally from the stanchion member. A substantially horizontal upper crease blade is fixed to each support member and has a lower crease blade pivoted thereto. The free ends of the crease blades extend away from the stanchion member and include applicator nozzles that are directed upward for the upper crease blades and downward for the lower crease blades. When a pair of pre-creased pants are slipped over the crease blades and the lower crease blades are pivoted downward, the pants are pulled taut at the hems between the pre-formed creases. As the pants are pulled off of the crease blades a pumping mechanism supplies a flowable, curable setting material such as silicone rubber to the applicator nozzles, which apply a coating of setting material to the inside surfaces of the pant legs along the creases.
