Daniel John Cotsakis 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).

  • Pressure sensitive tape for forming water-tight field joints in rubber membranes
    Patent number: 6120869
    Abstract: An adhesive roofing tape is based on a combination of brominated butyl rubber and EPDM. A non-diene block terpolymer is interspersed in the cross-linked polymer network. A plasticizer and tackifier are included to provide resiliency and permanent tack. An important aspect of the invention is to use a high molecular weight polyisobutylene plasticizer and a peroxide curing system. Rapid crosslinking without concomitant rapid degradation of the brominated butyl rubber occurs and some limited degradation of the plasticizer contributes to surface tack. A method of making the adhesive roofing tape is also provided.
    Type: Grant
    Filed: December 22, 1997
    Date of Patent: September 19, 2000
    Assignee: Carlisle Companies Inc.

  • Pressure sensitive tape for forming water-tight field joints in rubber membranes
    Patent number: 5686179
    Abstract: An improved adhesive roofing tape is based on a combination of brominated butyl rubber and EPDM. A non-diene block terpolymer is interspersed in the cross-liked polymer network. A plasticizer, a phenolic tackifier, a high melting point non-phenolic tackifier and a low melting point non-phenolic tackifier are included to provide resiliency and permanent tack at low temperatures. A method of making the adhesive roofing tape is also provided.
