DIRECTLY ATTACHING, HALOGEN-FREE, FAST-DRYING, HEAT-SEALING BINDER FOR SEALING POLYESTER FILMS TO POLYSTYRENE, POLYESTER OR PVC

The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

METHOD FOR MANUFACTURING JOINED BODY, JOINED BODY, AND HOT-MELT ADHESIVE SHEET
20230287246 · 2023-09-14 · ·

A method for manufacturing a joined body includes subjecting a first electronic component and a second electronic component to thermocompression bonding with a hot-melt adhesive sheet interposed therebetween. The hot-melt adhesive sheet includes a binder and electroconductive particles. The binder includes a crystalline polyamide resin and a crystalline polyester resin. When a melt viscosity of the hot-melt adhesive sheet is measured under a condition of a heating rate of 5° C./min. the hot-melt adhesive sheet has a ratio of a melt viscosity at 20° C. lower than a thermocompression bonding temperature to a melt viscosity at the thermocompression bonding temperature of 10 or higher.

Autobody repair formulation with improved control of work time and cure time at extreme ambient air temperatures

An Additive Package is provided to adjust the cure properties of a two-part bonding filler across a temperature range of from 4 and 44 degrees Celsius. A low temperature additive speeds a cure rate between 4 and 15 degrees Celsius and a high temperature additive slows down a cure rate between 25 and 44 degrees Celsius. The amount of Additive Package is varied to account for the desired cure properties. The Additive Package includes a first unsaturated polyester resins with an average degree of unsaturation of 70-100 percent based on total acid and anhydride monomer content. A process for repairing a vehicle body is provided using the Additive Package. A kit for accomplishing repairs in an after-market repair setting is also provided.
