<p>PURPOSE: An ultralow temperature adhesive sheet has excellent adhesion not only at 0°C or less but also even at about -85°C, thereby being used for an adhesive sheet for ultralow temperature refrigeration. CONSTITUTION: An ultralow temperature adhesive sheet is obtained by treating the rear side of a sheet with a pressure-sensitive adhesive and laminate-coating the sheet. The pressure-sensitive adhesive includes 40-50 wt% of acrylic rubber, 10-20 wt% of cyclohexane, and 30-40 wt% of toluene. The sheet is selected from an art sheet, a vellum sheet and a snow white sheet. Additionally, the ultralow temperature adhesive sheet is obtained by treating the rear side of the sheet with the pressure-sensitive adhesive and waterproof-coating the front side thereof.</p> |
