  • Patent number: 9925702
    Abstract: Disclosed herein is a novel approach to producing a seal. The seal is produced of a much lighter material than has been used before, produced by a process of mixing a compound containing uncured silicone and a volume of microspheres, and then dispensing this material into a mold. Such a mold will normally be a female mold having the negative three dimensional shape of the seal to be produced. The seal may then be pressurized and/or heated during the curing process either prior to removing the seal from the mold or after removing the seal from the mold.

  • Patent number: 9758386
    Abstract: A mesoporous metal oxide materials with a chiral organization; and a method for producing it, in the method a polymerizable metal oxide precursor is condensed inside the pores of chiral nematic mesoporous silica by the so-called “hard templating” method. As a specific example, mesoporous titanium dioxide is formed inside of a chiral nematic silica film templated by nanocrystalline cellulose (NCC). After removing the silica template such as by dissolving the silica in concentrated aqueous base, the resulting product is a mesoporous titania with a high surface area. These mesoporous metal oxide materials with high surface area and chiral nematic structures that lead to photonic properties may be useful for photonic applications as well as enantioselective catalysis, photocatalysis, photovoltaics, UV filters, batteries, and sensors.

  • Patent number: 9605113
    Abstract: The present invention provides curable compositions that are free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst comprising curable polymers having reactive terminal silyl groups. In particular, a silylated carboxylic acid is an alternative to organotin or other metal catalysts. In addition, the catalyst may be used with an amino-containing adhesion promoter or a mixture of amine-containing adhesion promoters and an amino-containing siloxane. The combination of these materials accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.

    Abstract: The invention provides for new viscoelastic silicone rubbers and compositions and methods for making and using them. The invention provides for viscoelastic silicone rubbers that are stiffer on short timescales than they are on long timescales. When subjected to brief stresses, they are relatively stiff and elastic, and they resist changing shapes. When subjected to sustain stresses, however, they are relatively soft and accommodating, and they gradually change shapes. When those stresses are removed, they gradually return to their original shapes. These viscoelastic silicone rubbers resist compression set and they are extremely resilient in response to sudden impacts. They can be dense rubbers, foam rubbers, and particles.

  • Patent number: 8785507
    Abstract: This invention relates to viscoelastic silicone rubber compositions that are the products of the reaction of: (a) a silanol-terminated polyorganosiloxane base; (b) a boron-containing crosslinking agent; and (c) a siloxane bond-forming crosslinking agent. In a viscoelastic silicone rubber composition of the invention some of the crosslinks, the siloxane crosslinks, are permanent and others of the crosslinks, the boron-containing crosslinks, are temporary. Because a fraction of its crosslinks can come apart and then reform, a viscoelastic silicone rubber composition of the invention can relax stress in response to strain and thus adapt to new shapes. The composition has sufficient permanent crosslinks, however, to establish a permanent equilibrium shape to which the composition will eventually return when not subject to any imposed stress.

  • Publication number: 20140186246
    Abstract: Methods are provided for synthesizing novel types of self-assembled siloxanes, such as polysiloxanes, with a sufficiently high density of amine functional groups to be useful for CO2 capture and release processes. Additionally, it has been unexpectedly found that some self-assembled polysiloxanes can be used for high temperature adsorption of CO2.

  • Publication number: 20140179815
    Abstract: Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.
