  • Publication number: 20150056757
    Abstract: The present invention relates to curable barrier encapsulants or sealants for electronic devices that have pressure sensitive adhesive properties. The encapsulants are especially suitable for organic electronic devices that require lower laminating temperature profiles. The encapsulant protects active organic/polymeric components within an organic electronic device from environmental elements, such as moisture and oxygen.

  • Patent number: 8921464
    Abstract: The invention provides hot melt adhesives that comprise a templating agent, a polymer and a wax. It has been discovered that hot melt adhesives with an effective amount of templating agent have improved heat resistance than adhesives. The adhesives find particular use as case, carton, and tray forming, and as sealing adhesives, including heat sealing applications, for example in the packaging of cereals, cracker and beer products.
