  • Publication number: 20240110013
    Abstract: A method of preparation of olefin-functionalized fluorosilicones, the properties of which can be optimized, for example, as release liners for silicone adhesives, the method including subjecting a mixture of a hydride-functional polysiloxane, a first compound having a terminal monosubstituted olefin, and a second compound having both a terminal monosubstituted olefin and an internal disubstituted olefin to hydrosilylation conditions to provide a hydrosilylated fluorosilicone with internal olefins and reacting the hydrosilylated fluorosilicone with internal olefins with ethylene in the presence of an olefin metathesis catalyst to provide the olefin- functionalized fluorosilicone. Articles including such olefin-functionalized fluorosilicones.

  • Patent number: 11700941
    Abstract: The present disclosure provides furniture pads having multiple segments that can coupled and decoupled to accommodate a desired size. The pads include a body of a protective material, with an inner segment and a first outer segment. The inner segment has at least one smaller cross-sectional dimension than the outer segment. Additional outer segments can have progressively increasing cross-sectional dimensions such that the all resulting segments are nested.

  • Publication number: 20230034952
    Abstract: Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier.

  • Patent number: 11472156
    Abstract: The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.

  • Publication number: 20210085080
    Abstract: The present disclosure relates to improved furniture pads that provide an opportunity to repair the connection between the pad and a furniture surface, the integrity of the pad, or both. In some instances, this can be accomplished by providing a pad comprising multiple pad bodies, each of which can has a protective surface. The pad bodies can be stacked or removed depending on the relationship between the furniture and the floor. In other instances, multiple adhesive layers are arranged on the top surface of a protective pad body, allowing for an adhesive bond to be refreshed and restored if the pad fails.
