Patents by Inventor Robert Ekeland

Robert Ekeland has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8722153
    Abstract: A release coating composition includes a curable polysiloxane and an aerosol suppressant that has more than one SiO4/2 unit. The aerosol suppressant includes the polymerization product of a siloxane and a cyclic polysiloxane polymerized in the presence of a polymerization catalyst. The siloxane has units of the chemical formula (SiO4/2)(RaRb2SiO1/2)x wherein Ra is a vinyl moiety, Rb is an alkyl moiety, and x is a number from 1.05 to 4. The release coating composition is formed by combining the aerosol suppressant and a curable polysiloxane. The release coating composition is also used to coat a substrate in a release coating process producing a mist of less than 50 mg/cubic meter measured at approximately 457 m/min.

  • Patent number: 7563515
    Abstract: The present invention relates to silicone compositions that can be used to control the interface at which release occurs when a bi-layer or multi-layer structure comprising compositions as separate layers, and a pattern of a different material sandwiched in between, is separated. The present invention further relates to a process that utilizes these compositions to control the transfer or release of patterns deposited on a substrate.

  • Publication number: 20070167563
    Abstract: A release coating composition according to the present invention comprises an alkenyl functional polysiloxane (1), a silicon hydride functional polysiloxane (11) and a catalyst (111) comprising a platinum group metal. The alkenyl functional polysiloxane (1) is an alkenylterminated polysiloxane prepared by siloxane polycondensation and/or equilibration using a phosphazene base catalyst followed by neutralisation with an acidic neutralising agent. The level of catalyst (III) in the composition can be as low as 2-40 parts per million platinum group metal by weight.
