Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape at 180 Degrees Angle
|Publication Date:||29 June 1990|
|ICS Code (Adhesives):||83.180|
These test methods cover the measurement of the peel adhesion of pressure-sensitive tapes.
Test Method A gives a measure of the adherence to a standard steel substrate or to other surface of interest for a single-coated tape (that is, adhesion to tape's own backing).
Test Method B gives a measure of the adherence to a standard steel substrate for double-coated tapes.
Test Method C gives a measure of the adherence of the release liner to the adhesive of either single-coated or double-coated tapes having a release liner.
These test methods provide a means of assessing the uniformity of the adhesion of a given type of pressure-sensitive tape. The assessment may be within a roll of tape, between rolls, or between production lots.
Variations in the tape's backing and adhesive affect the response. Therefore, these test methods cannot be used to pinpoint the specific cause(s) of nonuniformity.
These test methods may not be appropriate to test tapes having either relatively stiff backings, or stiff liners, or backings showing high stretch at low forces. These characteristics will result in a high variability of the test response which is not a true indication of the real nature of the adhesive bond.
NOTE 1 - A complete metric companion to Test Methods 03330 has been developed-D 3330M; therefore, no metric equivalents are presented in these test methods.
