Latest Patents

One of his notable inventions is a pressure-sensitive tape designed for forming water-tight field joints in rubber. This 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. The inclusion of a plasticizer and tackifier provides resiliency and permanent tack. An important aspect of this invention is the use of a high molecular weight polyisobutylene plasticizer and a peroxide curing system. This allows for rapid crosslinking without the rapid degradation of the brominated butyl rubber. Additionally, some limited degradation of the plasticizer contributes to surface tack. A method of making the adhesive roofing tape is also provided.
