[交流] 流变仪在压敏黏合剂中的应用

Three properties, shear resistance, tack and peel strength, generally characterized pressure sensitive adhesives (PSA). These properties are directly related to the PSA’s response to the application of stress and may be measured using rheology. For example, tack describes the ability to spontaneously form a bond to another material under light pressures within a short application time. As the contact time increases, higher shear resistance and peel strength properties (related to a materials long time flow behavior) are found. A single rheological test is described to directly determine the response of a PSA to varying deformation times, related directly to its shear resistance, tack and peel strength behavior.
