(1) ID numbers identify polymer data points in critical surface tension vs. contact angle chart.

(2) Names which are most widely used to describe the material or family of materials (e.g., polyurethanes and epoxies) at hand are preferred here. Commonly used acronyms and synonyms are also shown. To top of page

(3) CAS (Chemical Abstract Series) numbers are shown where available. In a number of instances, more than one CAS number is assigned to a given polymer — in some cases the details and nuances of these divergences are not at all clear. We have tried to reference the CAS number which appears to have the widest use with reference to the solid state properties of the given polymer . To top of page

(4) Critical surface tension in mJ/m2 (equivalent to dynes/cm), generally determined by the Zisman method (regression of the cosine of the contact angle), or by the wetting tension method (using solutions of 2-ethoxyethanol and formamide, per ASTM Std. D-2578). To top of page

(5) Contact angle with water, in degrees. The arithmetic mean of all equilibrium (Young's) and advancing contact angle measurements is shown. Generally, the equilibrium angle is similar to, but slightly lower than, the advancing angle; the balance of equilibrium vs. advancing contact angles from which this summary is drawn may have some effect on the average as shown for some polymers.
