  • Patent number: 7396869
    Abstract: The disclosure relates to using metallic acrylate compounds such as zinc diacrylate (ZDA), zinc dimethacrylate (ZDMA), among others for curing epoxy functional (and other cross-linking compounds), and to compositions containing such compounds for use in powder coat, film, adhesive, among other applications. ZDA and ZDMA containing compounds can also be supplied as an intermediate product that can cure the epoxy component of the compositions while being substantially free of conventional curing agents.

  • Publication number: 20070095463
    Abstract: A method and apparatus that produces shaped and laminate articles and recovers the excess material or flash as a part of the manufacturing process. The apparatus uses a combination of rotary die and anvil roller assemblies in successive multiple stations to cut and separate each raw material into final product portions and recyclable flash portions as each raw material enters the apparatus. The apparatus separately reclaims each raw material flash portion and delivers the flash of each material in a recyclable form to an auxiliary recycling operation. In recovering the flash, the apparatus does not adversely affect the speed or quality of production of the final shaped or laminated product. To ease removal of the flash, the apparatus applies lubricant to the blades of the rotary die. To avoid damage to web material, the apparatus uses vacuum belts to convey the web material and web product through the apparatus.

  • Patent number: 6902785
    Abstract: A laminar structure is disclosed that comprises a tacky mastic at least partially in contact with a ultra-violet (UV) light and moisture barrier. The structure can be employed for protecting a wide range of substrates such as wood, metal, concrete, cement, among other substrates. The structure can be cut or shaped into a virtually unlimited array of configurations. A release layer can be applied onto at least a portion of one or more sides of the structure. The release layer can be removed from the structure prior to applying the structure onto the substrate to be protected. Once applied the structure can protect the substrate from moisture, UV, microbial and animal attack.

  • Patent number: 6858260
    Abstract: A radiation curable, flexible, paintable composition produced from epoxy compounds and one or more polyol(s) has enhanced durability, thick and thin film adhesion, resistance to mold growth and dimensional changes while reducing solvent emissions. The composition can reduce, if not eliminate, runs and drips during the thermal bake cycles which are associated with using conventional compositions in automotive applications.
