Pressure-sensitive adhesive tape |
摘要 |
Normally tacky and pressure-sensitive adhesive tape, having a composite adhesive stratum made of 2 or more separate layers in which the tape synergistically exhibits properties superior to those of a tape made with either component layer alone. One layer is a polyurethane having some adhesive properties but lacking true pressure-sensitivity. The exposed surface of the stratum is a conventional pressure-sensitive adhesive. Numerical criteria are specified for each layer.
