Latest Patents

Shiraishi is named on one patent: Adhesive for Electrical Storage Device Packaging Material, Electrical Storage Device Packaging Material, Electrical Storage Device Container, and Electrical Storage Device. The invention describes an adhesive containing a polyol compound, a polyisocyanate compound, and an epoxy resin. Its polyol component includes an ester bond-containing polyol.

The patent specifies a stress-relaxation range for a cured adhesive film. After curing at 80°C for two weeks, the film is stretched to twice its length at 20°C and 65% relative humidity. The stress during stretching is compared with the stress after the film remains stretched for 100 seconds. The specified relationship is 10.0 ≤ (S1−S2)/S1 × 100 ≤ 40.0. This criterion defines a performance range for the adhesive in electrical storage device packaging applications. The patent count provided for Shiraishi is 1 patent.
